“One of the first misconceptions about anal sex is that it’s unclean because it involves butts. In actuality, your anus has natural bacteria that helps fight infection, and if you clean your body regularly, your butt is as clean as the rest of you. So you don’t need to wash yourself right before you check out anal penetration, although by all means, do so if it will make you or your partner more comfortable. However, you should definitely wash whatever implement you're using (a toy, a penis) so that it doesn't infect you with anything.”
