I find attitudes around mating rituals surprisingly traditional even among people otherwise ideologically opposed to anything traditional, and supposedly beyond old fashioned gender roles.

I find it puzzling and extremely alien the way many women who I find quite reasonable otherwise rather unreasonably, in my mind, refuse to make a move, instead hoping that their desired man will. But that's the way it is. This rule has barely budged compared to other sexual rules, which have changed enormously in the last 40 years.
