I can understand the appeal of the cougar to a young man, I’m one myself, so I get it, but there are men out there that are attracted to women older-like a LOT older, like 70-80+ year old women. I don’t even want to get into their minds to find the root of these attractions, many into the cougar thing are or were into mommy, but ones that much older, well, looks like some were into granny too and it’s left a hell of an impression in their minds.
Obviously many boys would have been babysat by their grandmothers as kids, and they’d see the same things many times they would if they were around their mom, getting dressed through a not totally closed door, getting out of the bath or shower, all kinds of things. Then maybe getting caught jerking off, that would be a real trauma I bet, since a person of an older generation might be a lot more strict and mean than their mom would have been and the sense of associating sexual pleasure with humiliation is then born and merged. Spanking fetish especially seems to be born from getting caught and then punished.
So they could be seeking to relive that sense of humiliation with another much, much older woman long after their actual granny is pushing up daisies. It’s funny how an incident from decades ago of only a fleeting moment can have lifelong effects on someone’s sexual fantasies and fetishes of what turns them on, the mind is a mystery to be sure.
