I wouldn't say it "grosses me out", it's more like, she'd either have MUCH more relationship/sexual experience than me and no pairbond capacity whatsoever anymore or be deeply mentally ill or ultra hyper high standards (how on earth does a foid reach 33 as a virgin, or even semi-virgin? I don't even know what my female equivalent would be since I only fucked escorts and there's no real parallel in female reality).
It's like, why do I have to be put in an advanced piano class where everyone already plays for 20+ years just because I'm older and around most people's age there, instead of being put in the beginner class, which consists of mostly younger people, who like me, have little to no piano experience?
Also, it's natural for men to date/marry younger foids anyway.
