Wanna know a bunch of ways you cannot get pregnant? This website tells you how. (The site disclaimer: This is a humor site, and, although it is educational, it is not intended to replace the advice of a medical professional. Remember, sex has risks. One such risk is pregnancy, another is becoming infected with a sexually transmitted disease. You should thoroughly educate yourself about the possible consequences of having sex before you go out and jump anyone. Remember, no form of contraception is completely foolproof. The only way to be absolutely certain you will not get pregnant is to abstain from vaginal sex…and artificial insemination…and in vitro fertilization…and you get the drift!)
