The time has finally arrived. I am going to buy the first cage. And I have some simple questions. First of all, we are not anything particularly sadistic or punishing when looking to play with or practice male chastity. It is the denial or at least postponement that is of the greatest interest for Madame and myself. 1) Are there cages that close and function without a lock? We are starting out with some session play and Madame likes the idea of the locking being part of the progression as we explore our options. 2) Any recommendations for a cage that allows urination while standing up? My prostate is large enough now that even under normal circumstances sitting makes urination difficult at times. 4) Madam likes the idea of metal cage feeling cool against her, um, flesh. But she has no actual experience with this sort of thing. Do these resin-based models like the Holy Trainer offer similar sensation? Any definite pros and cons between metal vs. non-metal devices? Thank you. And I hope I am asking these questions in the appropriate place.
