If men want monogamous/serious, they're laughed at for being naive/childish and not coping with how modern women want casual sex. If men want causal sex, they're a man child who can't settle down. No one tells a women complaining she can't get a guy to settle down she's a "girl child who can't cope in the new world of sexual freedom", they agree with her that the men are dogs. that same women wants casual sex, she's empowered.
