The reason young boys are not female raped more often by their female peers is because they are trying to figure things out, not reached a level of sexual confidence. The sexual encounter is about both of them trying to figure things out together. You put them in a cage with an older experience female predator, she will victimize them repeatedly.
I found out their tactics they use which would not work on an older man. They are highly sensitized to a female body, they can not rationally think. Sending pictures or grabbing their hands to have them touch her body. One teacher was laughing at how he ejaculated just from touching her. She wiped him off in her teachers office and finished sexually abusing him.
If I see a picture of a naked women, or a vagina dripping wet/leaking it does nothing for me versus when I was younger.
It looks consensual but it is not, many of these boys develop stronger pair bond with these women than at maturity.
