Coitus interruptus, also known as withdrawal, pulling out or the pull-out method, is a method of birth control in which a man, during sexual intercourse, withdraws his penis from a woman's vagina prior to ejaculation and then directs his ejaculate (semen) away from the vagina in an effort to avoid insemination. This method was used by an estimated 38 million couples worldwide in 1991. Coitus interruptus does not protect against sexually transmitted infections (STIs/STDs). From Wikipedia
