Here’s why you should consider using contraceptives, men discharge bodily fluids before the ejaculation phase and women also produce vaginal fluids during arousal, and the exchange of bodily fluids could cause pregnancy and/or sexually transmitted infections even if one pulls out before ejaculation.
The pullout method works about 78% of the time, which means that over a year of using this method, 22 out of 100 women — about 1 in 5 — would get pregnant. By comparison, male condoms are 98% effective when used correctly every time.
Not only is it not very effective, but withdrawal also isn’t a good method of birth control because:
It takes a lot of control for the man to pull out before ejaculation.
The woman has no control over it at all.
You may feel that it gets in the way of sexual pleasure.
Even if they pee before sex, the man can still release fluid before they ejaculate. This pre-ejaculate does contain sperm.
