Got about a third of the way through and could not finish. The world building was not good, you're thrust into a world with no context or exciting submersion into it. The main plot line is sex, but not in an interesting way between 2 characters - it's incest and rape. The matriarchical society is not well structured either, it's literally about chaining men by their dicks. The point when I gave up was when one of the lead ladies decided to cut a male characters penis off for entertainment.
