Speaking of peens: Tell all the uncut fellas you know that those after-sex showers may kill them. According to a study from Uganda, washing the penis minutes after sex increases the risk of acquiring HIV in uncircumcised men. But the best part?

Delayed cleansing—and longer exposure to the vaginal secretions—may then reduce viral infectivity." [NY Times]
