>>1179048>Penetrative sex, however, does nothing for her without massive amounts of clitoral stimulation.I've come to believe this is the norm. If you read a lot of physiological works about female arousal and erogenous zones (okay, read a few, because there aren't many) you'll find they used to think that vaginal orgasm was purely a byproduct of a sort of pull or tug placed on the tissue that during penetration stimulated the clitoris. Then some work was done into some erogenous zones inside the vagina, located not very far in, off to the sides. Maybe guys with unusually curved dicks have something going for them?
But yeah, the same rule doesn't hold for any two women. Frustrating in some sense, but exciting in others!
I'd be curious to see how much the average female under 30 actually knows about lactation/if they've ever seen it. My guess is that it's never crossed their mind and they just figure that whatever happens, happens.
