Hold on a minute. Ask yourself if you even WANT to get with a girl who has a lot of male friends.
Chances are, if she's a girl with a lot of male friends, it's because she thrives off of male attention. A lot of times girls that do this are girls who have some sort of Daddy issues in their life. Maybe their parents are divorced, so from a young age they were the first ones wearing make-up in middle school, looking for someone to fill that empty space in their lives.
Second, understand that guy friends are really not her friends. Unless they are gay, they are men who want to bang her but have gotten put in the friend zone, which could however result in sex one night if alcohol is involved. The moment you start going out with this girl, her male friends will disappear, and she will complain that "all my friends are gone!!!" (then when you break up, you'll see all the male friends begin calling her again)
Male friends feel intimidated by you because you are the one taking her away from them. They can start rumors to get rid of you. "Hey be careful with that guy, I heard he was bi-polar. I heard he was arrested for assault not too long ago." And most girls with guy friends tend to be very gullible, believing everything a man says, because like I said before, most of them haven't had a fatherly figure around to preach to them most of their lives.
So if you want to get with a girl who has a lot of male friends, thrives off of male attention and the fact that these guys all want to bang her, go right ahead. Be friendly and fun around all of them. Join in on conversations. Treat her friends like your friends, but understand they never will be. They may start calling you, maybe even hanging out with you, but the moment you break up you'll never hear from them again. Male friends want sex and her friends are not your friends.
