Yeah. I agree with what eastbay said. It sounds like you want male companionship and friendship, but you're afraid that in order to make it happen, you have to expose yourself to groups of men that make you flinch. To me, they're called "frat boys." And to me, you also sound like you suffer from the same issues that the lead character Paul Rudd played -- that movie in which he's trying to find a guy to take the place as his best man at his wedding or some such.
I agree that you should just hang out with guys because you're probably psyching yourself out, imagining it to be worse than it really is. On the other hand, you shouldn't feel pressured to immerse yourself in uncomfortable situations. I say, just do the things you like doing and, if guys happen to be there, make friendly conversation.
Needless to say, men are dealt a huge blow in this society if they can't act butch and rugged and insensitive all the time. Being someone who was never that adept with a ball, I think we fuck up our young sons out of fear that they won't be "tough enough," and they internalize that shame. And we're so jacked up by the process that we turn around and constantly check how manly we're being, and we judge other guys and put 'em down to make ourselves feel better, and we end up doing dumb shit like calling each other fags even if our dicks don't work that way. I think it's just as bad for gay people. That's why they do all that "straight acting" bullshit; it's because they are made to believe that all gay men are necessarily effeminate, and they end up turning on each other over some arbitrary bullshit. (Maybe they have it worse than we do.)
Either way, man, you shared something big. Great! Now let's do something about it. Keep us posted.
