No, I don't think so.
Some men get turned on by a fully clothed woman's boobs, but I rarely if ever glance at a guys crotch, I feel rude.
Even if I did, it wouldn't really do anything for me, though when I was a bit younger, I cringe, cause I used to stare at this guys dick in class cause he was wearing light coloured pants, and I was always trying to figure out if he was hard or not.
Literally everyone knew what I was doing, I think he was just very well endowed, and creeped out lmao. He never said anything about it though. I feel very humiliated thinking of it.
But looking didn't make me horny. I've also been sent unsolicited dick pics, not a turn on at all.
Though, if I liked a guy, it would probably turn me on, because that would be a dick I want.
Like if someone sent me a pic of spaghetti, I'd be like meh. But if they sent me a pic of chicken alfredo... I'm little hungry ;P Not everything is equal.
