I don't think there is any evidence that courtship and relationship building is any less fundamental a mating strategy than opportunistic assault, among humans. For starters, rape is seldom a reliable reproductive strategy in animals that require extensive child care, and is not even a good impregnation tactic in a mammal without clear and reliable fertility markers. So it seems unlikely that self-control is necessary to curb a natural impulse to rape in most men. Not even sublimation. The visible evidence is the other way around - a fairly large percentage of rapists (and other coercive or contractual situations such as prostitution) seem to be engaging in fantasy and pursuing a delusion, even to the point of needing some kind of role-played imitation of courtship and seduction, as if they were "sublimating" a need for willing cooperation.
