Some young couples adopt the contraceptive method of in vitro exclusion when they live in sex. This method looks simple and easy, but there are many harms. If they are not grasped, they may be pregnant.
In vitro radio ejaculation method, also known as drawing method or sexual intercourse interruption method.The in vitro ejaculation method is based on the physiological phenomenon of men.The climax of men is divided into two stages. In the first stage, semen is concentrated in the penile department, called "ejaculation inevitable" stage. After a few seconds, it reaches the second stage- "ejaculation stage".
When using the body radiation method, the man will inevitably pull the penis out of the vagina during the ejaculation of ejaculation. The in vitro sperm of the woman may contain a small amount of sperm in the secretion of sexual excitement, but it does not necessarily contain sperm, although there is pregnancy to cause pregnancyMay, but the probability is very small.The reason why it is not advocated that the method of ejaculation pursuits is because it is very difficult to control. If he can really control the in vitro ejaculation, you may not be pregnant.
The problem of in vitro radon can be triggered
But the ejaculation of the body can cause a very serious sexual problem: premature ejaculation.Men and women who use the body’s ejaculation method to contraception are the most common procedures for stimulating men in the prelude to a very excited stage. After inserting, they can be pumped several times and suddenly dial the ejaculation. This can satisfy the man and ensure that women will not conceive.However, because men and women are easy to fall into the traps of sexual psychology, they ignore the concept that men should help women satisfy at the beginning.Therefore, if it can’t be long, men will develop the habit of premature ejaculation.
In vitro radiation method contraception, beware of sequelae
Entry ejaculation will make young men who lack sexual experience develop a rapid ejaculation response. Men cannot sprint in the vagina until ejaculation, and cannot enjoy the climax pleasure freely.At the same time, both physiological and psychological, both men and women will think that the vagina is only used to make men with ejaculation pleasure.
Endogenesis method may be the most popular contraceptive method in the world, and it is also the lowest -efficiency method.According to statistics, if a hundred couples use this method to contraception, thirty women will get pregnant.
There are three reasons for the in vitro radiation method to fail: there are three reasons:
1. Sperm cells usually flow from the urethral mouth before ejaculation. Each drop contains about 50,000 sperm. If it flows into the vagina, a drop of semen can make a woman’s egg fertilization.
2. At the most tense stage, the timing of drawing the penis may be too late due to the pleasure of men’s attachment, so that some semen ejaculates in the vagina.
3. Sometimes after ejaculating in vitro, the man immediately stroked the woman’s pussy with his fingers, so that she had a climax, or it could not be separated for a long time.In these two circumstances, both fingers and penis may bring sperm into the vagina.
In vitro radio essence is not a good contraceptive method. Even if it is used in a safe period, the failure rate is still very high, and there is a possibility of developing premature ejaculation. Therefore, for couples who want to contraception shortly after the wedding, you can try tooling or drug contraceptive method.If you insist on using the body’s ejaculation method, maybe "lost the wife and fold the soldiers"!
