Did you just say woman enjoy sex? How come the ladies find many other reasons/excuse to deny it after men pitched in and helped the bulk of the housework etc?
Not 100% sure but men do enjoy sex and they pay premium to single women who love take advantage on this.
As one used to say women are good at faking orgasm but men are better at faking the relationship. Again not certain nowadays as women could be equally capable of faking both if needed be.
BTW, it is the old dude who needs the blue pill to keep the mojo, not the old Ladies. We're fortunate the latter do not wholeheartedly believe the Viagara/Levitra/Cialis commercials are trying to profit corporate coffer by creating EDs as a category of life threatening disease and brainwashing the men to pop those pills.
