It's not really about them being traditional. I have friends from all walks of life, sexuality, color, and gender, however, as a straight man I'd like a little more companionship with other straight men. There are certain topics I can't really breach with my gay male friends or my hetero/homo female friends, just like there are only certain conversations or experiences that I can share with my transgender brothers and sisters.
Let me clarify that I don't feel like this is an outstanding problem, I have great people in my life and don't feel like having a straight male friend or not will change my life too much. I believe that variety is the spice of life and I'd just like to see what that friendship would be like. I haven't been close friends with another dude in 10 years and have done a lot of growing since then.
Anyway, I really appreciate all the suggestions and hopefully I'll meet a dude that I click with soon
