When I used to watch hung studs in porn, I would get jealous of them, even though I was hung bigger than most porn studs. I recognized this as arousal. But because I'm not into men romantically, it didn't set off any alarms.
I would start lusting after seeing their big dicks and solid asses, and wanted to feel them up. But it wasn't like I wanted to breed them like a woman -- different feeling. I lusted more out of jealously, etc. It was very much competitive in nature. I would get aroused when I'd see their asses going up and down as they're a penetrating a woman. Of course, there are some men/porn studs that I have ZERO attraction to.
I still don't ever fantasize of sucking dick or getting my dick sucked by a man, or having anal sex with one (just being honest), It's just way more about feeling up each other when there is a woman present when the moment is right. If there is not a woman there, then it's less arousing in reality for me.
But, yes, visually-speaking, I like looking at well-hung studs with nice asses in porn. Love watching big, low-hangin' balls going balls deep and slapping against a woman's pussy. And those big cum shots.
What am I? Don't care. Pansexual, but like breeding with woman exclusively. Anal and oral sex with men is not arousing in general -- just some feeling up, and getting a possible handjob from one with a woman involved?
