"Voluntary" is a tricky term; what about the psychological pressure to
actively *reproduce*, as a goal (vs. mere sex-as-goal), that many

Drives can be flexible; if the goal is reproduction (vs. sex, as
above), it becomes fairly easy for any given subject to route around
birth control (even when desired by a given partner!).
