I just find it slightly more difficult to approach guys and ask them to coffee or study together. I find that you make guy friends either through sports or partying, so I've been doing more of both lately.
Anyone else find themselves a bit short on bros sometimes?
If you have a good number of friends (and as far as the ones that are die hard friends, always there, 4 is a pretty decent number) but most of them happen to be girls, that's fine. I agree with dougalmcflurry that it doesn't matter too much what gender your friends are if you haev friends.
Of course if you've just been girlcrazy and ignoring friendship all together, yeah, work on it, but don't go friend hunting or anything just open yourself up socially.
I don't have many guy friends either, but thats cos guys, as a rule, at my college tend to be complete pricks. The ones I do have are all legends, btw. But yeah. you've got aaaaages til your bachelor party, and you'll have plenty of guy mates by then.
Don't actively go out to make new friends who are specifically guys, cos thats not how friendships tend to work as a rule. Just sort of bumble alongl ike the rest of us, and I'm sure you'll pick up a few more along the way.
