I tend to see it much the same way as you
HecatesCats. It is really upsetting to think of young women and girls having to negotiate these sorts of expectations. I often wonder if this is part of the reason why young people are engaged in so much 'identity' exploration - instead of sex seeming like an exciting adventure to embark upon, it probably seems quite terrifying (to both sexes). Maybe some of the turn towards embracing different gender identities is driven by a need to establish some kind of control or boundaries around sexual activity.
I'm not really saying anything new there, I know, but sex and dating seems really scary these days. And of course, it makes women really, really vulnerable. If sexual violence is 'normal' and porn normalises men getting off on violently abusing women, then no doubt many women are having horrible, abusive sexual experiences and blaming themselves for not enjoying it.
