Introductions discussion

I’ve been practicing chastity as part of our daily life with my wife for quite a few years now. We have been married for 18 years and our intimate connection is fantastic. We have three daughters who are grown enough to handle themselves around the house independently. She isn’t entirely fond of the concept of wearing a chastity cage, though she does go along with it every once in a while for up to two or three days at most. I manage two businesses and oversee many employees. I am always the decision-maker, responsible for others. For me, there is a great thrill in “letting go” and handing over control to my wife regarding all things sexual. I consider myself a self-proclaimed masochist, and my wife excels at this; she enjoys inflicting pain on me and loves biting, chewing, and general CBT, which I find wonderful. She has a wild streak where she occasionally dominates me in the bedroom to some degree, yet still holds back slightly. I don’t care for sissyfication or cuckolding dynamics, but my wife controlling my penis and orgasms drives me crazy (in a good way). I absolutely LOVE providing pleasure to my wife while I am locked up. She prefers natural penetrative sex; NO Dildos or foreign objects allowed. This is a strict rule because I have tried using them before. She permits me to perform cunnilingus on her, but again, it isn’t something I get to do very often. She feels self-conscious about her vagina, though she reaches an orgasm quickly when alcohol is involved. Afterward, however, shame sets in and she shuts down. I have attempted several times over the last couple of years to draw her deeper into this world, but she endures it and accepts my fetish without too much complaint. So I play a game where my wife acts as an unaware keyholder, keeping the keys in her bags during business trips, etc. I send photos and updates, though often with little response. Yes, I continue playing because there are occasional moments when she plays along, and boy does she have a cruel side (which I LOVE). I also love and adore my wife deeply, so an outside keyholder is not even a remote possibility for me. She is wonderful, being the fuel that ignites every sexual fantasy even after all these years! I would like to see her more involved or interested. I came across this site hoping to find kindred spirits and learn more. Perhaps share experiences and get advice from people in similar situations? Perhaps gain a woman’s perspective on all these matters?
