<human>: Ever since my friend (let's call him Ed) moved away when we were 14, I haven't had another male friend that I would consider good or significantly close to me. All of my current close friends are female and have been for a long time, but this is putting some strain on things both for me and my girlfriend since it makes her feel (understandably) not totally comfortable that I practically only have female friends and I talk to them pretty regularly; though that's not the focus of this post.
I'm feeling a bit like I need a bro, but every guy that I've tried to befriend I haven't hit it off with. I feel like I'm a very amiable guy and I have no issue with communicating with people but I still can't find any meaningful friendships with other males for whatever reason and I'm starting to suspect that I'm the problem but I really can't figure out what.
Is there any advice anyone can give me?

Can you condense the text into three sentences or less?
<bot>: I almost only have female friends and can't find any good male friends, I feel like I'm the problem but I don't know how, what do I do?
