lol well that's just your preference. I am the same way with straight men. for whatever reason, I've never had straight male friends. at least not real friends. usually guys only talk to me when theyre interested in me romantically or sexually so that doesn't leave much room for friendship. guys are very like into their "brotherhood" I guess ha ha I know a lot of guys who pride themselves on not having female friends. well, if you think that's part of what makes you a manly man, then why would you want women as friends? not that this is your situation, but I'm just giving an example.
its not a man/woman thing though because I have several close gay male friends. theyre men. I think its the way society conditions men and women to interact within their groups and with one another, the differing ideals of femininty and masculinity, the traits that we adopt that we are taught are for men and for women, etc. gay men half of time just say "f*** society" and go their own way, and sometimes that's a direction which is more closely related to the way women are socialized. also there's no sexual agenda with them, so their feelings and egos aren't as wrapped up in little things. over the years I've noticed that straight men are INCREDIBLY sensitive and insecure, just masked beneath a superficial veneer. its very unattractive but understandable considering societys demands. the smallest negative comment or reaction from a girl he may actually be interested in, but is trying to be "friends" with is likely to send him on an irrational path of "what a f***ing bitch." its very common. that's one of many reasons I don't have straight male friends. I have no problem with my gay male friends though. I love them and a couple of my life long besties are gay men.
to each is own. you don't have to be friends with everyone.
