I find it difficult to understand the animosity towards guys because of their sexual preferences and feel the need to use insulting words. It's not as if they pose any threat to anyone, although that's how it appears to me.
Men and women have a large sexual spectrum, there are feminine guys and masculine girls and everything in between. As for myself, after a lifetime of appreciating, lusting after and enjoying a huge number of experiences with women, find myself wanting to push the barriers, as one guy said earlier, it's the adrenalin that becomes addictive and I agree. I have had a few MMF sessions with married couples and sucking a guy off while fucking his Mrs for example is something that I found to be very enjoyable and would look to repeat. I can honestly say that I didn't find the guys attractive, just their cocks! Personally I would never want anything up my ass and I don't particularly like giving anal, I've only done it once with a WG and it didn't really do much for me. I would certainly like to meet a TS and am actively seeking such an experience. Now, I'm sure that I will be denounced for being a faggot, queer, bender, ass bandit, etc etc which is fine but as I don't find men attractive I don't think that's the correct terminology.
It's a little bit more complicated than "if you fuck a bloke in a dress, then you're gay" or maybe I am gay, OMG I better change my Facebook status immediately!
