You can read the complete text of author Greta Christina's "5 Stupid, Unfair and Sexist Things Expected of Men" HERE (and I hope you will), but below is her list:
1. Fight, fight, fight!
2. Be a good husband/partner/lover -- but don't care too much what women think.
3. Be hot to trot. Always. With anybody.
4. Stiff upper lip.
5. Fear being perceived as gay.
