I think you'll find that's completely normal. Even totally str8 guys are fascinated by huge cocks. Having a huge cock is a bit like owning a supercar, get it out and guys will want a look, even if they don't want a ride from you!
I mostly look at lesbian porn these days.
But I can also be turned on a lot by a cute girl working a big cock.
Yes, I'm straight, but the part of me that does not object to seeing a cock on screen must be my gay side. It's more like I imagine I am that guy then the girl doing the work... if you wanna trade places with the girl then you should start to ask yourself... :biggrin1:
