STD’s, i need to know?

Asked by Your Neighbor on June 13, 2014

okay, say there is a guy and a girl, both virgins, and no STD’s. they have sex. but the guy goes and has sex with a different girl, with no STD’s as well. and so on. if the guy takes girls virginity and they have no diseases, could the guy develop an STD? even wearing a condom? Or would he be clean.
