For me, I know that while I find women attractive, I'm not sexually attracted to them. I love men, and their cocks.
That being said, I am open to the idea of playing with women (in a threesome or group setting, or something like that) if there were an understanding that it was just about having some good clean (dirty?) fun with nothing emotional attached to it. I mean, I'm fascinated by guys and their equipment, and I do enjoy playing with my own. Playing with another woman would probably be pretty fun as well.
I also think that in general, people are too focused on labels and trying to compartmentalize and categorize *everything.* Based on what I've observed and what many people have told me, sexuality and gender identity are a continuum or spectrum more than an absolute.
