Men are adult human males. Women are adult human females. If you want to talk about the social roles that men and women occupy, you should use the appropriate words, which are not "men" and "women".
FWIW, I try to use "male/males" to refer to sex, and "man/men" to refer to gender, since AFAICT, there are no terms that clearly refer to gender.
"men" and "women" should not have their meaning diluted. They already have the meaning of "male" and "female".
