Is it normal i'm sexually fantasise a guy sucking my dick though i'm straight?
I've been wondering that for a long time, I never had an relationship with a guy, nor I want one. And never hook up with a guy before. I had few relationships and sexual relationships with women before (and now). so I'm sure I'm straight. Admittedly I'm always horny.
But I always sexually fantasise a guy suck me off (and very very rare occasions imaging what's it like by sucking a guy's cock). There's one time after I had a swim and head back to the shower, there's a gay guy next to me came over and try to suck me off by kneel in front of me and start taking my swimming trunk off, I was thought about letting him to suck me off but then I got scare and turned away. Also I had a gay friend who ask for my dick pic and jerk off in Skype, and I did do a favour for him.
So is it normal to have sexually fantasies like this or by showing my dick on screen?
