Seven lies in female contraception

Many women who have a more accurate menstrual cycle can calculate their safety period. Women's menstrual cycle is divided into a menstrual period, ovulation period and safe period. In general, there is no egg exclusion during the safety period. At this time, there is no need to worry about the problem of sperm entering the body to fertilize the egg.

But you may not know that the sperm can fertilize the egg within three days after it is discharged, but there are also reports that the sperm still retains fertility after one week of sex. Although the ovulation period is in the middle of menstruation, due to the external environment, temperature, mood, health and other factors, the ovulation may be advanced or delayed.

Therefore, the method of safe contraception is not reliable at all. In general, the method of safe contraception is only applicable to couples who have regular menstrual cycles, long-term cohabitation, regular living, and cooperation and understanding between the two parties.

Lies Do not be afraid of trouble

 What method are you using for contraception? The contraceptive pill that you must take every time before sex does not guarantee the safety of "emergency" sexual behavior, have these short-term contraceptive measures already annoying you?

In fact, in addition to condoms used in vitro, oral contraceptives, built-in contraceptives, etc., there are many quite effective contraceptive methods you do not know yet. For example, an intrauterine device that must be placed in the womb by surgery. All it needs to do is to prevent fertilized eggs from growing in the womb.

Generally, as long as there is nothing abnormal, it will not cause trouble to sex for a year or two. Although intrauterine contraception does not guarantee that you are not infected with sexually transmitted diseases, it is indeed the most effective method of contraception. Once inserted, you can forget its existence, and only have a 1% failure rate.

This long-term contraceptive method is undoubtedly the most effective and convenient. But it also has unsuitable people, such as those with extreme postuterine flexion, endometritis, salpingitis, vaginitis, uterine fibroids and other gynecological diseases, or those with excessive menstrual flow and secretions. If you are interested in intrauterine contraception, go to a regular hospital and ask an experienced doctor.

Lies Mikasa's contraceptive effect is the same for anyone

 On the market, only a few contraceptives are indicated on the package. Is it suitable for people to take the same effect?

In fact, women who are overweight have a faster metabolism and need more hormones to prevent conception. They will be hindered by too much fat in the recipient during contraception, which will greatly reduce the effect of the drug, and it will be difficult to get rid of the weight effect when "creating a person." Therefore, they should be careful when choosing the appropriate contraceptive and "creating" method.

Moreover, many contraceptives have a fat solubilizing effect and may stay in the place where fat accumulates in the body so that it cannot reach the blood that it should go to really take effect.

I would like to remind you that if you weigh more than 58 kg, it is best to ask the doctor to recommend other more reliable methods, such as an intrauterine contraceptive device, or a combination of contraceptives and condoms to ensure foolproofness.

Four lies Contraceptive effect is good

Do you think it is foolproof if you take contraception? You must know that when a doctor tells you how effective contraceptives are, that's also based on proper use. Although contraceptives and condoms advertise their effectiveness as high as 99% and 97%. However, in actual applications, the real effective rates of the two are 94% and 86%, respectively. That is, it does not have 100% effective contraception at all.

To ensure that the pill is effective, it should be taken at the same time every day. You don't try to combine taking with daily life, it can help you remember time better, such as taking it every morning after brushing your teeth.

In case you forget to take it, read the precautions carefully and see what you can do to make up for it. Women who choose a condom can apply some lubricating ointment if they have less secretion, which can be tightly fixed to prevent slipping, and the effect is better.

Lie 5 If the penis does not fully enter, that is to say, the man ejaculates in the woman's vulva rather than in the vagina, the woman will not become pregnant

The fact is that it is possible for the sperm to enter the vagina and continue to move towards the uterus.

 How does real contraception work?

The so-called contraceptive principle is to use scientific methods to prevent and destroy certain links in the normal conception process to avoid pregnancy and prevent fertility. There are many contraceptive methods currently used. According to their contraceptive principles, they can be summarized into the following methods:

(1) Inhibit ovulation of the ovary

 There are female short-acting, long-acting contraceptives and subcutaneous implant contraceptives that have the effect of inhibiting ovulation of the ovary. The development and maturation of egg cells are affected by the hypothalamus and pituitary gland. Such contraceptives can inhibit the function of the hypothalamus and pituitary gland to prevent the development of egg cells, thereby achieving contraceptive purposes. In addition, women also have the effect of inhibiting ovulation during lactation, so they can prevent pregnancy.

(2) Inhibit normal sperm development

 The gossypol extracted from cottonseed can inhibit the normal development of sperm. Long-term use of gossypol can significantly reduce or completely disappear the sperm count, thereby achieving the goal of infertility. This male contraceptive has not yet been promoted. In recent years, some places have used physical methods (such as ultrasound, microwave, warming, etc. to stimulate the testes) to inhibit the spermatogenic function of the testes, and some progress has been made.

(3) prevent sperm and egg from binding

 There are many methods of this type of contraception, the purpose of which is to prevent sperm and eggs from combining to achieve the purpose of contraception. For example, condoms, vaginal diaphragms, etc. prevent sperm from entering the vagina, or sperm entering the vagina cannot enter the uterine cavity; topical contraceptives have a strong spermicidal effect. Putting them into the vagina can kill the sperm that has entered the vagina. Prevents sperm from entering the uterine cavity; male and female sterilization can prevent sperm from being discharged or prevent the sperm from combining with the egg; it is a permanent contraceptive measure; during sexual intercourse, in vitro ejaculation or perineal urethral compression is used to make semen excrete Shoot your bladder outside the vagina or retrograde so that semen does not enter the vagina.

(4) Prevent implantation of fertilized eggs

The uterus is the place where the fetus is conceived. If you try to interfere with the internal environment of the uterus, it will not be conducive to the growth and development of fertilized eggs. Placement of birth control rings in the uterus and various family visits contraceptives can change the endometrium and prevent the implantation and development of fertilized eggs.

(5) Staggered ovulation contraception

Staggering ovulation contraception is contraception during the safe period, that is, using the menstrual cycle push algorithm, basal body temperature measurement, and cervical mucus observation method, etc. to master women's ovulation period, avoid ovulation sexual intercourse to prevent contraception, so that sperm and eggs miss the opportunity to meet.

 Contraception methods commonly used by men

Although there are many contraceptive methods that people can use at present, there are relatively few contraceptive methods for men. Commonly used are condoms, vas deferens or occlusions, and other contraceptives such as oral contraceptives, external insemination, and perineal urinary oppression.

A condom is a male contraceptive tool currently used. As long as it is used correctly, the contraceptive effect is better, but some people are unwilling to use it because they are afraid of affecting sexuality or using it.

Vasectomy ligation or blockage is a type of sterilization surgery, which is suitable for couples or wives who are no longer having children because they are unable to have children.

Although oral contraceptives for men have been successfully researched, they have certain shortcomings and cannot be promoted.

Extracorporeal ejaculation and perineal urethral compression methods are not easy to master properly, so the contraceptive effect is not reliable, and few people use them now.

Contraception methods commonly used by women

There are many female contraceptive methods. Commonly used are contraceptives, birth control rings, tubal ligation or blockage, vaginal diaphragm, vaginal contraceptive rings, and other contraceptives such as safety and lactation.

There are many types of contraceptives, including short-acting contraceptives, long-acting contraceptives, family-visiting contraceptives, subcutaneously implanted contraceptives, and topical contraceptives. Among them, the most effective short-acting contraceptives are used. Up to 100%. Long-acting contraceptives are only used once a month, and some can be used once every 2-3 months; it can reduce the trouble of taking pills every day, and the contraceptive effect is slightly inferior to short-acting contraceptives. Implantation of subcutaneous contraceptives can prevent contraception for about 5 years. Since it has not been produced in China, it is currently imported and cannot be widely used. Family visit contraceptives are quick-acting contraceptives and are mainly used by visiting couples and also by newlyweds. The main effect of topical contraceptives is to kill sperm. Among them, the contraceptive film is the best, and the contraceptive ointment is less effective.

The iliac birth control ring is currently the most widely used long-acting contraceptive tool. Commonly used are stainless steel round rings. This kind of birth control ring can be used for contraception for about 20 years. The disadvantages are the high shedding rate and the pregnancy rate with the ring. The contraceptive effect with the copper birth control ring is better, the drop-out rate and the pregnancy rate with the ring are both low, and it has been widely used in various places.

The vaginal contraceptive ring is easy to use and the contraceptive effect is good. It has been promoted in some areas.

Vaginal diaphragm is more troublesome to use. If the placement technique is not properly grasped, it will easily lead to failure, so it cannot be widely used.

Oviductal sterilization is a permanent contraceptive measure. One operation can be used for lifelong contraception. It is especially suitable for women who no longer have children or who cannot bear children due to illness.

Contraceptive methods in the safe period and lactation period are not easy to grasp correctly. It is easy to cause failure, so it should not be promoted.

How to ensure that contraception does not fail?

 Learn to use condoms, vaginal diaphragms, and other external contraceptives properly, or you will fail. If the use of external contraceptives fails (such as condoms rupture), timely remedial measures should be taken to prevent pregnancy.

In short, contraception is a long and arduous task, and you can't be paralyzed at any time.

The most unbelievable five contraceptive methods, women should pay attention

Lactation contraception

Non-lactating mothers usually resume ovulation and resume menstruation after 4-6 weeks of delivery. Most lactating women do not have menstruation. Some people think that breastfeeding mothers will not ovulate and will not conceive without menstruation. In fact, this understanding is wrong. Breastfeeding mothers may resume ovulation even if they are not menstruating. If not contraceptive during this period, it is very easy to cause the woman to "darkly." Therefore, nursing mothers should also contracept.

Pee contraception

Some people think that after men and women have sex in the same room, letting the woman flush the vagina by urination can prevent pregnancy. This is a confused understanding. Women's vagina and urethra are two different organs. After men and women have sex in the same room, it is impossible for the woman to urinate to sperm out of the other channel.

"Safe Period" Contraception

The so-called "safe period" refers to the 7 days before menstruation and the first 8 days after menstruation. People also call it "first seven after eight". This time is not the ovulation period for women. At this time, the couple is in the same room, and the woman is generally not pregnant, so people call this period the "safety period". But the "security period" is not absolute security. Because some women ovulate irregularly. Some women have regular ovulation, but when their mood, living environment and physical conditions change greatly, their ovulation will lose its original regularity. Therefore, it is not safe to use female safe contraception.

Vaginal irrigation contraception

Some people think that after men and women are in the same room if the woman has a vaginal flush, she can prevent pregnancy. This method is actually very unsafe. In the same room, if the man ejaculates, countless sperm will soon swim into the woman's uterine cavity. At this time, no matter how the woman performs vaginal flushing, she cannot flush all the sperm out of the body. Therefore, using the vaginal irrigation method for contraception, the woman can still get pregnant.

If the woman is breastfeeding or menstrual, if you have strong sexual desire, you can choose to buy a love doll to solve your situation, so that your girlfriend or wife will not worry that you will be derailed.

Sex toys effectively improve women's sexual life satisfaction

Do you know? A potentially important gap in sexual relations in bedrooms is often unknown. A new research survey published in the Journal of Sexual Medicine showed that 15% of female participants stated that they did not have any sexual pleasure or felt only slightly during sex. This ratio is only 4.6% among male surveyors. This difference in feeling between the sexes is called "difference in pleasure". Janet Lieberman and Alexandra Fine, both graduated from the Massachusetts Institute of Technology's Department of Engineering and Mechanical Engineering, also have a master's degree in clinical psychology from Columbia University.

Of course, this does not mean that the device they developed is the first device to improve the lives of both sexes, but most of the related devices in circulation on the market today will be quite awkward or difficult for users to use, which is more or less a departure The original intention of developing this kind of equipment was described. Lieberman told the media that she and her engineer husband were not even able to operate products purchased online by Amazon, which is why they came up with the idea of ​​developing an EVA. Then they relied on Dame Products to produce the first innovative product designed to increase sexual intimacy and were disappointed that they couldn't find a satisfactory product that improved sexual intimacy. The two young people in their 20s decided to shake their own The entire sex industry.

The core of selling EVA is also an advantage: EVA is extremely comfortable: the flexible sides of this design vibrator allow it to be used in any position to ensure safety. Lieberman's professional background in product development is also an important reason for successful development. Why can't sex toys have the same development standards as ordinary electronic products consumed by consumers? Lieberman's frank development of EVA was not easy.

"Although the design of EVA looks very simple, in fact, we use a series of 3D printing technology and complicated measurement formulas to make it look less obtrusive and more concise," Lieberman said.

However, her efforts were not in vain. In the Indiegogo event that ended last month, they raised more than $ 500,000 and 6620 supporters, and their goal was only $ 50,000. Through online crowdfunding, EVA A total of $ 575,452 was raised, which makes it a successful example of online fundraising in the adult industry. Since the two raised enough funds, they were able to produce two different colors of EVA: lavender and light green. If you miss this event, you will still see the launch of EVA soon: Lieberman is supervising the mass production of EVA in China, and the launch time is expected in May this year.

The success of EVA may be an important turning point in the sex toy industry, and at the same time, it can encourage businesswomen to have more innovation opportunities and courage in the industry. Over the past half-century, the sex toy industry has developed into a multi-billion dollar industry, and this field is mostly dominated by men. It is worth mentioning that Lieberman is the first and always the only female engineer above her current position. She served as the engineering representative for a copy production mini 3D printed desktop project at MakerBot, and this project won Five awards presented in numerous publications at CES.

The adult industry is developing more and more rapidly, and the development of these love dolls is being replaced by intelligent AI more and more rapidly. It is mainly because people in society now have a strong desire for 'sex'. Stress and lack of sufficient time at all can only use adult products to solve themselves.

When does male sexual function begin to age?

I believe that every man is very concerned about his sexual function because this is the proud capital of men. However, sexual function varies from person to person, and the individual differences are very large. Some are still alive and well and sexually active when they are 70 or 80 years old, while others are young and face impotence and premature ejaculation. So when does normal male sexual function begin to age under normal circumstances?
The main cause of sexual aging in men is due to degenerative changes in the testes, which subsequently cause changes in the brain, pituitary, adrenal glands and sexual function. Men generally start from 50 to 60 years old. With the increase of age, the testicular mesenchymal cells can gradually undergo aging and degenerative changes, which greatly reduces the secretion of testosterone and the volume of the testicles. With aging, sexual function gradually declines. After 60 years of age, testicular shrinkage is more obvious, so it can be said that testicular function plays a key role in male sexual function decline.

Elderly male penis erection takes longer and requires increased direct stimulation of the genitals. After 60 years of age, the penile erection intensity and ejaculation volume of men are usually reduced to varying degrees. Good physical fitness and a strong body are extremely important for maintaining good sexual function. In addition, other factors can not be ignored, such as social, psychological, etc. may affect human sexual function.
When you reach middle age, you should be in good health and have a good marriage. However, a significant portion of men in their 40s and 50s have significantly reduced sexual function. The main manifestations are slow sexual response, low semen volume, extreme fatigue after sexual life, and the refractory period (the time between two consecutive erections and ejaculation) is greatly extended. The feeling of being overpowered and underpowered added to their lingering annoyance. The main reason is that the pace of modern life is accelerating, men are under heavy work pressure, have more entertainment, stay up all night on tobacco and alcohol, and are prone to physical decline and sub-health.
In fact, although sexual function gradually declines with age, if it is well maintained, sexual function can be extended along with life.

In fact, there is a love doll to accompany you at this time, which may also make your tired body feel a little comfort.

How to provoke female sexual love

When should we have sex It doesn't matter when you have sex. It is important that you and your partner let it happen in a comfortable situation. Some people like to have sex at dawn, some people like to have it in the afternoon, and some people like to have it in the deep night. More important than time is time. Give each other more time when you first have a relationship. Weekends are ideal but include at least one full day including sleep time.

Should we eat or drink something before we have a relationship? Don't overeat, it will only make you want to sleep. Eat small amounts of food and do not drink too many alcoholic beverages. A little alcohol will help you relax, but it will also make the man's erection slightly more difficult, but anyway you will spend more time in bed than in the bathroom, right? Where should we have a relationship? Important point. Finding a place where you can have more than forty-eight hours of privacy is not an easy task for those planning to devote their age to virginity. But it's worth it. Cars are no longer big enough to have sex inside, and there isn't enough privacy outdoors, there are too many bugs, sand, and unwanted branch wood.

 A comfortable bed is still the best choice for sex. It's best if you can have your own room, comfortable, warm, spacious, and a bathroom--Linyu together. If you are going to have a relationship, you may have touched each other before. Take the time to get familiar with each other's bodies slowly. That's what sex is all about.

 What should we prepare?

Prepare something that will make you feel comfortable. Birth control supplies, condoms, or your favorite pillow or bathrobe.

What should I do at first? You can't expect him to know what to do to make you feel comfortable. You have to tell him or show him, which means you have to take a little initiative and take his hand to a place where you feel comfortable. Take it easy. If this is his first time, he may be nervous about what you are going to do, and maybe his penis will not respond at first. Patience, gentleness, and understanding are ways to regain vitality. It may not be easy for you, but that is why we tell you to give yourself more time.

Does it hurt?

Perhaps you have heard many terrible stories about how painful it can be to lose your virginity. For some women, it can be painful, but with the right contact and the right partner, you can incorporate the penis into your body without pain. Let him take it slowly, use lubricating oil, slowly press his fingers into your body, and slowly relax you. Tell him when he feels comfortable and when he feels uncomfortable.

What sex position should I take?

Many women like to be in the upper position when they have sex for the first time to control the movement. Others prefer to be inferior and give control to his lover. Find the best pose for you. Just remember to tell him to take your time, don't worry, and if you feel the need, use a lubricant.

What if I can't get an erection?

This sounds funny, but your penis, which has been working properly for several years, may give you a fatal blow the first time you have real sex. That's normal because you're too nervous. Take a deep breath. Do something else with your hands, your lips, and your tongue. Try to forget your anxiety and your penis will respond. This is only a temporary problem.

If I were a virgin, should I tell her?

 Many men think that because they are men, they must take control of sexual behavior, and they don't care who has rich experience. If you are a virgin and she is not a virgin, tell her and let her dominate if she wants to. Learning to gain experience is also a sign of love. Don't be afraid, to be honest. Many women would rather you feel inexperienced than stupid, and they will be happy to guide you to the world.

Do we reach the climax at the same time? Don't worry about each other if they reach the climax at the same time. Some women do not get orgasm during sex, or even if your girlfriend can get an orgasm, there is no way to guarantee that you can reach orgasm at the same time. Enjoy it and trust her to tell you how she feels.

 What should I do if I reach the climax too quickly?

If you really reach the climax much earlier than you wish, take your time, take a break, and try again. The second time you should be more relaxed. And be prepared to take your time-so is your penis.

Is my size big enough? Still too big?

Is the shape normal? Another common problem is size. On average, the length of the penis is about 5 1/2 inches during erection, which is far longer than the length needed to hit the main nerve area of ​​the vagina, including the legendary G spot. The vagina can be expanded to fit a larger penis, or it can be contracted to fit a smaller penis. Size has nothing to do with your ability to be a good lover.

Another common question is about shape. Some men are worried because their penis is bent a little bit downwards or left, etc., and because they don't see men like them in porn movies, they assume they are abnormal. Others worry that if they bend down, it will be difficult and painful to have sex because the vagina is not the same shape as their penis.

Remember that there can be many different positions for sex. The penis and vagina can fit into each other in different ways, and each new pose may bring new pleasure to you and your partner. Some people believe that a bent penis makes oral sex much easier.

Will I be a good lover?

A good lover does not happen naturally. With the right partner, the right time, the right care and practice, you have what it takes to be a good lover.

If you are touching a girl for the first time, and something very embarrassing has happened, in fact, don't worry, you may need a tpe sex doll to show you about women, so your girlfriend will not say some very embarrassing questions.

Sex toys are innocent! Please treat the concept of using sex supplies correctly!

Why the adult products industry has always been on the verge of traditional industries because some conservative ideas have caused people to be biased against adult products and adult toys. The reasons for these prejudices are the following reasons:
    1. People who think that sex life is inconsistent use sex toys
In fact: anyone can use sex toys. Surveys show that people who have sex use more sex toys than people who do not have sex. Partners who use sex toys usually have a higher quality of sexual life and better emotional intimacy. About 20-30% of people use at least one-time toys in their lifetime. Sex toys are not life-saving straws or a panacea, they are just a supplement to sex games.
2, it is generally believed that the use of sex toys will be addictive
In fact: Addiction means some kind of harm. Proper and reasonable use of sex toys will not hurt you. Although some people may become dependent on the habitual use of sex toys, you do not need to forcibly quit. Anyone can easily return to masturbation or have sex with sexual partners without sex toys.

3, feel that men only use sex toys when they can't get real sex
In fact: When people think of men and sex toys, men who buy masturbation tools and then masturbate while watching AV. But the truth about men and sex toys is that millions of men use them, whether they are in a relationship or single. Use sex toys to get to know your sexual response. Whether using sex toys or not, masturbation is a key way to learn how to control your body. The use of sex toys does not mean that the man is a "loser." He is actually very smart and is likely to perform better in bed. Because he is passionate about sex and more focused on skills.
4. Many people feel that using sex toys makes sex unnatural
In fact: We hear a lot of incorrect claims about sex. One of them is that natural sex means only physical contact. So is it not natural to draw with a pencil and paper? Of course not. If we use tools or toys to make it more interesting and not make sex unnatural, sex toys are not activated by batteries, but by our imagination.
5, some sex toys are good, some are bad
    In fact: Except for those that may be dangerous, sex toys are not good or bad. Sex toys are all about how we choose and how to use it. A vibrator may be too strong for one person, but it may be perfect for another. The trick is to find the sex toy that works for you. Most sex toys are liked by some people and disliked by others.
6, sex toys look weird
In fact: weird and normal are relatively speaking. Maybe you find it uncomfortable to talk about these in public, but as long as you realize that everyone can be "weird" behind closed doors, your sex life will be more Happier and easier. Sex toys don't make sex weird, it only means that you find sexual pleasure worth pursuing.
7. The use of sex toys may cause harm to the body
    Truth: There is no evidence that sex toys can damage your sexual sensation or genitals. Of course, there are some dangers if it is not used correctly, but this is like a bottle opener. No one will throw it away because it may hurt your hands due to improper use.
  Adult products and sex toys are necessary for sex life. As long as you choose safe and reliable sex toys, you can add more fun and passion for sex. Think about it, if you use such a trendy sex toy in your daily routine sex life, is your sex more passionate?
