I think this is good because a girl who bangs other men is also a girl who is strong and independent and doesn't need a man to survive. Hence this girl will help the man she is dating instead of being an anchor on him. That is the man will end up being better off because his girlfriend can bring more to the table in terms of social and sexual experience (so he is better off in the same way he would be better off if he had a stock that was paying a dividend). When I let my girlfriend bang other men at the start I was hurt but after a while I wasn't. This is because society teaches us that this behavior is unacceptable while in reality it is just as acceptable as a girl having friends other than her boyfriend. Hence if enough people do it, people will find it normal rather than hurtful and we will all be better off.
