Lol, well, I was also joking. I don't buy into faddish midwit sex-based biological determinism as a serious answer for everything. Reductio ad absurdum.
But now that you mention it, approval of another person (getting laid, among other things) is external. If not, then women who supposedly do x to fit in, keep up, or attract someone are equally driven by internal forces.
And from some comments itt, apparently a mattress on the floor and a single floor lamp + crucified Jesus doesn't shouldn't keep women out of your bed. (It may keep them from coming back, though. Calculated risk or learned helplessness, you decide.)
