There has been a very large and, at times, extremely heated debate about chastity in the Mansion recently. Arguments raged about whether one particular style of chastity was better. Both sides accused the other of foul play, saying that they had said neither was better and claiming the people in the oppposing camp were attacking them for their style of chastity. The person who started the entire thing was hero or villain, depending on your particular viewpoint. It's just as well the expensive silverware had been put away or it could have been used as a weapon.
The best chastity suits the needs of the people who use it. To say that yours is a very self centered perspective and excludes people from discussing anything with you. It shuts down debate and only allows an argument.
You are not the only person who uses banding and numbness to create a chaste environment though it does seem that your own technique is more extreme. Does that make it better? Our Administrator uses banding and is very happy with his set up. His wife enjoys sex with him but he is never allowed an orgasm. He is however allowed to get an erection, just not one he can feel.
My Wife is my Mistress and keyholder. She likes using tease and denial and likes the fact that I can feel my penis. She enjoys seeing me erect, very occasionally likes making me cum, always likes controlling my access to my penis. Your style of chastity would be completely abhorrent to her. Does it make it wrong? Better? Worse?
Another mistress might only be interested in holding some keys. For her the very idea of tease and denial is ridiculous. It has no place in a chaste relationship. All she wants is worship and service. The purest form of chastity, for her, is simple. Men lock their penis up for her and stay that way for as long as possible. If their penis is completely numb the entire exercise becomes meaningless. Is she right? Is she wrong? Is your chastity better?
Another Mistress demands that her submissive husband has genital reassignment surgery. His penis is to be removed completely, he is to be forevermore denied sex with his Wife of many years. He wanted her to cuckold him and, after years of nagging him, she decides to do as he wishes, but at a terrible cost. He can have as much sex as he wants, but only with men, and never again as a man. A limp, unfeeling penis to her is a wasted opportunity and utterly ridiculous. She wants her mans penis to be turned inside out, the glans turned into a clitoris. She wants to watch her former husband be fucked by other men, watch him orgasm, but only from penetration. Is she wrong? Is her idea so extreme it doesn't count as chastity?
Personally I think that you are too gentle. You should consider a penectomy. After all, that would be the ultimate sacrifice for your Mistress. It would show that your subservience to her is complete and unending.
(Actually that isn't what I think, but hopefully you can see my point about perspective.)
