Pulling out, also called "withdrawal" and "coitus interruptus," is risky because the guy has to be totally aware of when he's going to ejaculate (cum). Then, he has to have enough self-control to pull out before he cums, every single time. Just one mistake can result in an unplanned pregnancy.

A lot of guys are unable to have this much control, especially when they're so close to the pleasure of orgasm and ejaculation. Plus, a woman can get pregnant even if a guy ejaculates just a little bit of semen near the opening of her vagina, because sperm can swim inside.

Safer sex is not just about preventing unplanned pregnancy. It's also about keeping you and your partner healthy - and free from sexually transmitted diseases (STDs), which can be spread both through pre-cum and vaginal fluids.

Pulling out is better than using no birth control at all. But it's unreliable and gives no protection against STDs. Are you really ready to take those chances?
