I've been talking with my wife about this (checking to see how
crazy or plausible the theory was) and she added another
element: what if women decided that since life comes through
them, they were going to be more responsible with who they
chose to sleep with i.e. if he's only interested in having
sex, he's probably not the one...or if he deals drugs, why
would I want to set myself up to possibly be a single mother?
