Chastity and orgasm denial discussion

I’m curious if any of our lovely KHs manage to apply the device on their own. Is it occasional? Regularly? Always? This is something I find incredibly erotic, and I suspect I’m not alone in feeling this way:-) Do you share that erotic thrill? Or do you see it as just another routine task? The sensual aspect is wonderful, yet it’s also the biggest hurdle. My wife and I have attempted to let her secure it herself on numerous occasions… But the moment she reaches out with her hand, my erection starts rising:-( It seems to be the specific instant where controlling myself becomes most difficult! Still, she has succeeded in locking me up twice now! The first attempt involved sending me off for a round of masturbation after each failure… The process was lengthy and tedious since I had to reach climax five times before my shaft would finally submit. During that fifth time, the session dragged on quite long. Not particularly enjoyable. The second try went much better. She instructed me to recite Lord Byron’s verses until I softened sufficiently! The initial attempts failed, but as a Frenchman reading English requires focus, she then asked me to apply proper intonation and breathe life into the poetry! Lost in the words, suddenly… I felt the cage sliding up my shaft. Click! If you manage to put it on yourself, do you have any strategies worth sharing?
