BROS OVER WHORES???????

So i was talking to this boy pal of mine and i was like don't boys have a code like girls do about relationships. Its common knowledge to girls that you never ever date your friends ex and you never let any man come between you two and so i was wondering if boys had the same code too. He told me that p***y is p***y and that you don't c**k block your homeboys unless the boy truly likes the girl and sees her as wifey material in essence any guy friends girl is up for grabs from the word hi when she is introduced to the buddies. Then it dawned on me why so many of my galfriends have been hit on by the ex's friends and they feel its disgusting whilst the boys think its cool....men are indeed from mars and women from venus!
