Well, Mike, I have always been turned on by men being intimate with one another. I think maybe because everything is externalized with men. You can see that they are turned on, you can see the orgasm. With women, well, they can fake it. Also, in lesbian porn the kissing pretty much sucks and they are doing it for the men who watch. I hate lesbian porn unless it is with real lesbians and there is a site for that which I do enjoy. So, I don't totally understand myself why I like it, but as you said "the world is even more varied in sexual taste and desires than I realized."
