That's not true.  Being overtly self-aggrandizing to women is a turn off.  It makes sound like you are trying too hard to impress her. (Cockiness works, but not overt boasts).<p>Men do need to be more aggrandizing in professional life.  Men do not carry a baby to term and nurse it for years.  All they bring to the mating game is wealth, status, and genes.  Thus, professional success is much more important in order for a man to attract a mate.  Thus men are much more aggressive and do whatever it takes to rise the ladder.<p>On the flip side, when a women is self-aggrandizing it is quite a turnoff to a man.  It much more actively harms her reproductive success.  So women learn not to do it, and that rubs off in professional life.
