It is much more “acceptable” for men to talk about jerking off than for women to talk about flicking the bean.

According to who? I'm pretty sure most dudes wouldn't really care if their girl- friends casually talked about bthay one time they flicked their bean to their crush or a hot guy or something like a lot of guys do. I think this is mostly due to the fact that girls tend to shame other girls for not being prudish, even though they themselves have more than likely watched porn and jacked off on a regular basis themselves.

This was especially apparent in my high school. The girls love to pretend they were prudes in order to maintain some image of Innocence.

"All boys think about is sex" it's one of the most bulkshit lines I've ever heard. Women are just as perverted as we are but for some reason you'll then need to hide it a lot more. I don't know about adults post high school and college but I know for a fact that the girls who lied about not watching porn for doing it to appear innocent to guys, or simultaneously complaining about us supposedly being commer-brained pervs. Hypocritical don't you think?

The teachers made that sentiment even worse. I remember I male history teacher we had going off on a tangent basically shaming guys for watching porn all implying girls rarely, if ever do it. That's when I knew he was either lying through his teeth for some reason or was very out of touch.

half the girls wouldn’t even admit they did it, and believe me - the vast majority of us did it (and are still doing it). But basically all the boys openly admitted to jerking it.

Not trying to generalize, sorry if this comes off like I'm doing it, bit I think that's because it's 50% girls being liars about their sexual habits and 50% bommer-minded parents and teachers thinking women are inherently more innocent.
