Rafael My wife has been kept belted by me for nearly a year, and I generally check twice a day. Mostly I'm looking for signs of injury or damage, because even above keeping her safe from masturbation, it is vital to me that her health be preserved. I'm willing to inflict discomfort to achieve virtuous chastity, but not actual damage. I check the lock on general principle, though.
When I've been belted -- a state I am probably going to return to permanently soon -- I actually appreciate being checked frequently. To me, wearing a belt is exchanging my autonomy for attention from my keyholder. A negligent keyholder is worse than no keyholder at all. I feel safe and protected when my keyholder pays close attention both to my health and to ensuring I can't masturbate under any circumstances.
