Who said anything about foreplay?
She can be asleep. In fact, I think it's hot.This is sage advice. Turn her down once and she'll throw that shit back at you every time you want it and she doesn't for the DURATION OF THE RELATIONSHIP.
Not only that, it's fallacious. I can't screw if I'm not hard. If I'm hard, I'm not gonna say no. She, however, can put out regardless of her level of horny. It's like comparing apples and vaginas.
