Gender is a range of characteristics used to distinguish between males and females, particularly in the cases of men and women and the masculine and feminine attributes assigned to them.
Depending on the context, the discriminating characteristics vary from sex to social role to gender identity.
Please use this tag to identify questions which are of the "male vs. female" type, e.g. "Are men more aggressive than women?", for the psychological and social aspects of sex and sexual activities in general.
