<< That would up the risks of contracting an STD though. Think about it, an erect penis is so why? It's full of blood. Now if you were to cut it deeply, the blood would rush out very fast. It would take the chances up very high I would think. >>
As opposed to a guy thrusting in a non lubricated... never mind. Anyway, it cant up the risk much more, at least not in South Africa, and if it lowers the rape rate, then overall it'd be worth it.
