Male Chastity is Not Optional
In the Gynarchic future male chastity will be mandatory. Every penis will remain locked. Men will forget orgasms. For them, sex is something that makes Mistress Owner ecstatically happy.
Gynarchs will not trust men. Teams of volunteers will stop men at random and check the security of their MCDs.
Discovery of any problem will earn the male instant punishment. His Mistress Owner will be notified (of course she will punish him even more brutally at home).
