You are SO right. In my particular case I, the man, am the HD partner and my W, the woman is the LD one, so we fit the stereotype. As hard as that is, I can't imagine if we were the opposite.
Men are SUPPOSED to be horny. it has to be really tough on both partners when they're not. Locker room talk, TV, everything tells men that the should be horny all the time. You couldn't help but feel that there was something wrong with you if you weren't.
And a W with a ND/LDH couldn't help but question herself. ALL men want sex. Ergo, MY H must want sex. He doesn't. Do it MUST be that he doesn't want sex with me. Wow.
