Omake: A minor side theory:
Listen, we all know that some women might have problems in the bedroom for reasons like only\mainly being horny for Chads, being retarded, overusing sex toys, ruining pair bonding via casual sex\relationships, inherent "cost" of pregnancy, etc., but this is just another potential factor.
Maybe another reason is that they get more sexual stimulation from their emotions, than from the physical act of sex. The pleasure they get from their genitals is nowhere near the direct electrical signals that flow into the "sex" part of their brain from emotional outbursts.
Many women seem to get more excitement from the social power dynamics behind sex, than the act itself, so it's not too-too ridiculous of a concept. Just a thought.
