Hey WomanK - You're absolutely right! Men are equally behaviorally possessive about their women as women are about their men. I covered this a little bit in a former article on GirlsChase, here: http://www.girlschase.com/content/pleasure-loving-man-bring-out-womans-w.... The big difference is in focus - men care about sex and sexual fidelity, whereas women care about commitment and emotional fidelity. Thus a man is more concerned with his woman cheating/sleeping with someone else (even once) whereas a woman is much more concerned about her man having an extended emotional affair with another woman.
