No, men are just as bad at choosing partners as women. We are just so big-headed that we never realize that we are wrong.
Women will choose a partner that they think will be with them for a long time, to raise children. Why? Because after sex, women will be in a life-threatening scenario for 9 months. You might consider that as being easily manipulated.
Men are the ones who have no problem sleeping around. We are just as easily manipulated by women so that we can get sex.
So in the end, both genders are equally able to be manipulated.
