If you ask any expert in behavioral endocrinology, they will inform you that men indeed have more voracious libidos than women on average and that this is in part explained by the stark difference in testosterone levels (the male vs female distributions are so different they don't even overlap). One of the obvious ways to see this is the stark difference in sexual promiscuity between homosexual males and females, where the former have exponentially more partners and more sex.

If you don't trust me, read up from the bonafide experts. Carole Hooven's book T: The Story of Testosterone is a good option.
