Not a Sin? Why not? May be because it is hers and she grew it and she can give it to who ever she want to weather she is married or he is. So the sooner a man understands this he can act like Bro's before Hoe's. But in a way thats might be how he should act, because unless a man takes it from the woman (rape) It was her choice not his. So Honey do get mad at me she put it on me. Come on man you know it was not my fault your girl screwed me It's not liked I raped her don't get mad at me its her fault.
Any way you look at it it's a sin to get between what God brought together!
