I think it's important that sissies have their pp locked up. Real men should swing free, sissies need to be in chastity under lock and key, with Domme/Dom keyholder.
Sissies should pee sitting down, and should be punished if they try to pee standing up like a man.
If the Domme / Dom gifts a sissy with permission to masturbate, the sissy shoud remained locked and ONLY be allowed to masturbate like a girl - either using two fingers to rub her clit, 9r if she us being rewarded, allowed to use a vibrator.
But really, a sissy's locked clit should mostly be ignored. A sissy should learn to use her mouth and boi pussy as her main sex organs.
