There are three reasons why interrupted intercourse is not reliable to prevent pregnancy. First, it implies that the boy pulls his penis out of his partner’s vagina before ejaculating.
What happens if he does not leave on time?
The boys will admit that it is very tempting to move it inside, with the result that the sperm can achieve their biological destiny: fertilize the egg. Also, boys do not always know when they are going to ejaculate. Second, even if he takes it out before ejaculating, it may be too late.
The pre-ejaculation may already be in the vagina, and the pre-ejaculation contains sperm. Even if they remove the penis from the pod before ejaculating, they can bring sexually transmitted infections, and they can also infect their partner.
Finally, this type of “birth control” leaves the woman without any control. As she is the one who risks getting pregnant, at least she should have the same possibility of choosing an effective method of birth control.
What happens if only the penis is inserted for a second into the vagina?
One second is enough for the sperm of the pre-ejaculation to start swimming through your vagina. If the penis goes in and out very fast. Even so, it is called a sexual act, and the unprotected sexual activity can lead to pregnancy.
