why do you think there's so much rape in yaoi?

i personally do not understand why there's so much rape in yaoi. and it's not a recent thing either. alot of older yaoi(finder series, gravitation, dakaichi, etc) have rape in it. and some of the older resident fujoshis still talk about those in nostalgic way, even though they know it did have rape and SA and other problematic elements in it. all the popular yaoi have mostly been filled with rape, no matter the time. why do you think this normalisation of SA comes from? if yaoi is mostly catered to women, doesn't it make more sense that women would feel negatively about rape in stories since women are victims of such crimes irl more than men?
so what could be the possible reasons? is this some kind of sick rape revenge mentality? or is it a sick fetish of wanting to rape men if they were a man?
it's something that feels so misogynist even though i cant put down a finger where.
i want to know this from a person who's been a "resident fujoshi/fudanshi" and was in the yaoi genre early on (late 00s or early 10s maybe?) I have been in the BL community since 2018-19 and rape is something i have never understood. i personally don't read yuri this much, but overall yuri doesn't have this much normalisation of rape (as much as i have seen atleast). that doesn't mean yuri genre doesn't have problematic stories, it just isn't as mainstream to have a rape scene in yuri.
so why do you think yaoi has so much rape and SA? what could be the reason behind it?
