lol At some of these responses.
If a woman wants to cheat on you, she's going to do it. Trying to restrict her from seeing people won't do anything. I'd say a woman is more likely to cheat when she goes out with her girls than going for coffee with her male friend. The majority of the attached women that I have met, I met them while they were out at a bar with their girls.
In general, I don't mind if my woman has male friends. I have female friends. I think the guys that can't fathom why a man and woman would hang out together have limited experiences with females. I have female friends that I genuinely enjoy the company of. I can acknowledge their attractiveness without acting on it. Just because I find someone attractive doesn't mean I have to fuck them.
I'm not a bonobo, I can control my sexual desires. And just because I find a female friend attractive, doesn't mean I want to be in a relationship with her. I have some great, attractive female friends---but we would be horrible together as a couple. I wouldn't throw away our friendship for a quick fuck. There's too many girls in the world for that.
On the flip side, I don't think that all women and men are capable of opposite sex friendships. So, it does depend on the person. Like in this thread, guys who don't have experience being friends with a female would only be thinking about fucking. I wouldn't trust one of you blokes hanging out with my gf, obviously. And there are girls that are so naive, that they don't recognize when a guy is truly their friend, and when he is just trying to bang. I'd need to be with a girl that could make that distinction.
