I can't say this with regard to all guys. I do think I am able to make friends with some of them. But the vast majority of them I can't. There seem to be three strata.

(1) men who I can make friends with who are friendly with me but probably won't ever be deeply friends.
(2) men who tolerate me but will probably never understand me and would prefer not to around me.
(3) men who have disliked me from the first moment they saw me.

It is number three that stymies me. I suspect number three is due to "my look" which must scare them. And these particular type are usually uber serious about themselves and need ego stroking. My personality is one that can't take myself or anything too seriously. So if they do.. I am a threat to that. Finally usually whatever I am doing I want to be good at. If I am good at it and effortlessly seem to know what I am doing and it takes a great deal of effort for these men, they seem to get upset. Clearly that is "their" role.
