It depents one the person rather then the gender if he/she is complex, though men seem to be a litle more simple minded then woman but this dosn't mean there are no complex men.
Men are espaicely more simple minded when it comes to relationship's they proberly think difrently about relationship's, and when it comes to sex there aren't many men how wil walk away from a woman how is hitting on them.
Men how are complex are most of the time so complex that no one can make sence of them, but then again they could also be difrent from most people.
But both men and woman think difrently about sertain thing's this can be in a relationship but also in normal life, it hapens most of the time that men don't understand woman but it can also hapen the otherway around.
Though it also depents on how people are raised if a guy grow up whit 4 sisters he wil understand woman much beter then a guy how dosn't have any sisters at al.
