I love men. I love strength, hairiness, stubble, the way men act, the way men think, they way men dress, all those things that make a man a man. It's nothing that I ever chose or decided, it's just how it is.
I don't hate women or vaginas, but as far as sex goes they just do nothing for me. I can't explain it but it doesn't hurt anybody either way so I don't think it particularly needs explained.
I would not be surprised if male homosexuality (like mine) is ultimately discovered to have a different cause from female homosexuality. This is not scientific at all but in my experience men are homosexual because they/we LOVE men.
Women are often homosexual because they don't particularly like men, and women are there. Female sexuality seems more "fluid" than male sexuality to me, where men are mostly "set" as either gay or straight, but women have more "wiggle room."
