Yes, and I think the disparity is also because women may also have high sex drives, the risks and costs for sex are significantly greater for women than for men. Women are more susceptible to STIs than men, as well as other complications like UTIs; women also face pregnancy risks. If and/or when men & women have kids, women tend to bear more of the burden of childcare and other domestic responsibilities. After having kids, women’s incomes and earning potential tend to decrease, while men’s incomes tend to increase with the greater number of kids they have. So when considering men’s and women’s libidos, we also need to take the biological and social realities into the picture.
