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.

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.
