given women's hypergamy and men's koreogamy (=preference for young women) a free sex market benefits only part of the population, specifically alpha males and young females failing many others who are left with only a limited number of partners if any and a sex/love life much different from that one glamourized in the MSM. that's why I believe monogamy was invented as a form of sex communism, giving 1 woman to each man as a reward for his contribution to the community and his abiding to laws in order to keep every male citizen satisfied. this model was partially disrupted by the sexual and cultural revolution of the 60s. my personal opinion is that society is slowly becoming conscious of how a free sex market is not for everybody but will this lead to a restauration of a more rigid pre 60s life style or virtual reality and sexbots will be the real game changers in a more or less distant future? I definitely favor the second option.
