I dont think many women understand the effects of Testosterone. Usually when women hit their 40's they begin to feel and understand what it feels like.
I remember watching some Discovery show where a women researcher had rubbed some testosterone ointment on herself and testify that she could now understand high powerful the effects are and dont blame the way guys behave the way they do. The feelings are quite persistent.
