Men should be men, and women should be women.
I don't want to sound old fashioned but if the man becomes to effeminate, then where does that leave the woman?
You can not have a healthy relationship if both of you are trying to be the woman.
Look at gays/lesbians, in most cases one takes the feminine role and the other the male role.
A man should take care of himself and try to look good and healthy.
But guyliner, I think most guys can't get away with it.
