I like to watch, but only if I'm legit interested in the human being the penis is attached to.
Me and my guy have just watched each other masturbate to completion. I fucking love it. But I'm obviously super into him. Watching rando dudes whack it in the camper?? I'm more likely to giggle than get off. Not because I think they're pitiful or pathetic, but really when humans masturbate it's objectively funny as fuck when you remove the arousal. Imagine watching sex without being turned on, it's pure comedy.
I don't have to love/feel "romantic" feelings for sexual partners, but I do have to be attracted to more than just looks too get off in a situation where I'm not just watching a prerecorded event.
It's not at all difficult to see penis as a woman in society. Matter of fact we see them even when we don't want to, didn't ask to... It can be invasive and offensive. I only look at pics here if I find the person interesting in posts or if they have a badass blog.
Looking just to look, seeking that interaction online? I don't have to. At all. And to be honest I don't know any women who would. If I do they haven't communicated to me that they want to see what you're offering.
