Withdrawal is the oldest form of birth control on the planet – sometimes called “the pull out method” or “coitus interruptus”. There’s not much to explain, really. The guy pulls out before he ejaculates. End of story. The key thing to remember is this: The guy has got to do it right—every single time—for withdrawal to be effective. Gals don’t have much control. If you lean toward this method because of concerns about hormones, the cost of other methods, or something else – we urge you to check out other methods, too. There are other non-hormonal options and changes in health coverage may make any method affordable for you.
