Not quite sure what you're looking for here, but I have some thoughts!
I know that the fact that a lot of people enjoy porn can give a different impression, but what I've gleaned over the last 20+ years of working in sexuality is that a lot of people aren't into the genitals of people they aren't actually already intimate with. (It sounds like you're not talking about the genitals of partners or people you're dating, but instead about things like sexual media or your imagination, since you're saying "see" in a sexual context, not engage with?)
In other words, I actually think it's very common -- especially among younger people, but also in general -- for people not to exactly be "attracted to" genitals like it sounds like you're thinking. It makes sense, honestly: they're kind of like guts, a very intimate part of us. I'd also say it's pretty common, again, especially for younger people, to feel repulsed seeing genitals of people you're not already intimate with, and certainly when you aren't even asking. Same goes for seeing people being explicitly sexual when that isn't something you want and are seeking out. I suspect more people also have that reaction to men, even regardless of sexual orientation, because of how prevalent male sexual violence is.
Per the third person, that doesn't surprise me, either. A lot of people like to role play or be omniscient in their fantasies.
I think some of what might be going on here is a presumption about how everyone else is vs. you, when, in fact, a lot of people have a whole lot of specifics when it comes to this stuff.
