Being the sex expert that you are (sexpert, as we like to call ourselves), you'll know *everything* there is to know about doing the bad thing. Getting pregnant by having sex standing up? Pffffffffft. Making a baby by literally bumping uglies? Silly.
But not everyone is endowed with sensual prowess like you. Some have to work hard to gain that knowledge, deprived of opportunity to explore and learn on the job (fuck other people. We're talking about fucking other people).
Read these confessions by sex squibs and be proud of your all-knowing status (OK fine, you might learn some stuff on the way too).
