I think with aids, you can prove he was positive and knew he was positive, before he had sex with you. If he didn't know, then there is no case....
But with this thing....what should a woman do? Save the rubber and hope there is some DNA he left inside it, before removing it? And then what? Run to the ER to get swabbed for his juices inside her and DNA from that....? Do you video tape consent agreement of using a condom? Video the sex scene from all angles to show him removing it, if he was going to do such?
I'm just having a hard time figuring out how the law can be enforced?
Maybe just having the law, is enough to deter the guy from doing it????
