I don't think men want sex substantially more than women. What causes an imbalance, IMO, is that women value casual sex substantially less than men for a variety of cultural and biological reasons and women's value in the casual sex marketplace have a much flatter distribution and is also front-loaded when you look across the age spectrum. This means most women either can pretty much get casual sex whenever they want or at least have lived through a phase where they could. Meanwhile, most men will never live through a period where casual sex is as easy to get as it is for the median woman at her prime, which may permanently alter the perspective of many of them and cause them to consider casual sex more valuable, regardless of their actual level of sexual desire.
