Withdrawal is often referred to as ‘pulling out’. Withdrawal is used during sex to reduce the risk of pregnancy. Withdrawal is when the penis is pulled out of the vagina before ejaculation (cum). A person must not ejaculate near the genitals. Pregnancy can occur if sperm is near the genitals or in the vagina.
With typical use (not following the exact directions) withdrawal is 78% effective. It requires self-control and it can be hard to stop and withdraw the penis before ejaculation.
