"The second type of guy, and I have had them, will try to tell YOU how you are not "normal" and that "every other woman he has been with has been able to O from intercourse alone, so what is wrong with YOU"."
LOL, I had to laugh at this. Sadly, it seems a majority of men think that (1) they are the ones who can tell when a woman is faking an O, (2) women don't fake Os with them, and (3) that they reliably make their Ps O through intercourse alone. Yet, despite their Ps having reliable multiple unfaked Os through intercourse alone, their Ps don't seem much interested in sex.
What is wrong with this picture? (1) they can't tell if a woman is faking, (2) their Ps fake Os with them and have their attention on acting rather than being genuinely present for the sexual intimacy, so (3) their Ps don't make them O reliably (if ever) so sex gets pretty darn uninteresting. The woman in this cycle has at least as much ownership in perpetuating it as the poor guy in the dark. But it is a pretty ugly cycle that is incredibly difficult to break, in no small part because of the delicate male sexual ego.
