Also, while matriarchal societies exist, certain social characteristics of gender-bias have biological roots. It's the gender that doesn't get pregnant that does the risky stuff, and so males are valued for bravery more than women who stay at home to rear the young. The males can't nurse the children so you can't change this gender role. Thus, male gonads are the symbol of bravery.
Rules of courtship have a lot to do with making sure of the father of the baby (the mother being known), without using dna testing or magic, because inheritance goes by father. If inheritance goes by mother, the father of a baby doesn't matter so much so the woman being a virgin before marriage doesn't matter so much, so a woman being "easy" doesn't matter. Thus is a matriarchy boys wouldn't develop a bad reputation by sleeping around.
Also, a single chemical is linked to aggressiveness and facial hair. If your females are aggressive (not just by social contract but naturally aggressive) they should have deep voices and beards and not have tits.
