I have a long story too but unfortunately no blog to refer you to. so you will have to read it here.

I will try to make it brief or at least what passes as brief to me. Married for over 40 years and spent most of it living with my wife and sharing her girlfriend. FFM threesomes were our "normal" form of sex until a few years ago when we moved away from our girlfriend. PIV and sharing a bedroom with my wife has not been allowed for longer than any of us can remember. My guess is about 30 years.
Our previously wild and fun sex life ended when we moved far away from our girlfriend who was supposed to follow us but could not at the last moment. My wife and I had a hard time adjusting to being just a couple again. We began to drift apart after a very close relationship. Intimacy was going down the tubes so I was determined to do something about it. There was very little that the three of us had not at least tried sexually over the last 4 decades. Although we had flirted with teasing and denial before, it was always just one of the two ladies in my life leaving me high and dry after sex until the next day. Not a very long time but sexually frustrating while it happened.
I always had a fantasy of my wife or girlfriend asking me if I loved them enough to not cum again. It was a hot fantasy for me for a long time since orgasm seeking was my goal throughout my life. I talked to my wife about T&D again since she always complained that male ejaculation was disgusting and messy. This was a way to have her orgasms, tease me and not have to deal with the aftermath. We did it a few times and my wife loved it. She would laugh at my sexual frustration and said that she felt in control of our sex life for the first time in her life. She wanted me to stop masturbating because I was doing it 5 or more times a day to relieve stress and my high sex drive that was suddenly not being taken care of.
I went on the honor system and was doing well. My wife had noticed how much more I responded to her teasing when she did not allow me to cum for longer periods of time. She also enjoyed not having to deal with me post orgasm when I can get very grouchy. Plus no more stained bed linens and towels. At some point I read about chastity devices in a T&D forum and looked into them. They had changed since the old days when it was one size fits a large penis only. I showed the CB6000s to my wife and she readily agreed that I should buy one. I did and after I put it on I was instantly aroused by the sensation of something gently gripping my penis. This made me more aroused inbetween orgasm days.
My wife steadily increased my no orgasm time until we reached 6 weeks at the end of 12 months. It was then that my wife asked me if I wanted this to be our sexual lifestyle from now on. I asked her if she had her way, how often would she let me have a pleasurable orgasm. She said that since she dislikes PIV sex and prefers her vibrator to even sex over a threesome, she really had no need for my penis other than to perform her wifely duties. She said if she really had her way, I would never have an orgasms anymore in any form but she recognized prostate health and my physical needs. She does love me more than she has loved anyone else even though she leans more towards females sexually. As she says, she is drawn to the person, not their sex but all things being equal, she would choose a female over a male. Lucky for me she has not met a female she loves more than she loves me. She does orgasm easily and intensely with me and does enjoy me making her cum. However, she is not a big fan of making me cum. She likes to make me hard to show her power over me sexually and validate her attractiveness in her old age.
What started at strictly T&D turned into long term chastity. I am currently only going to have one ruined orgasm every 4-6 weeks and no pleasurable ones for 4-5 months. My wife wants to limit my pleasurable orgasms to Valentine's Day, my Birthday, our Anniversary and xmas. That gives me two 4 month periods and two, 2 month periods per year. She would eventually like to reduce that to once a year if she sees that I can handle it. She is not going to force me to do anything that I cannot handle and that does make chastity much easier to do. We do not do D/s or pretend I am forced into chastity and cannot escape. I can always ask to be let out anytime I want but do not. We just do chastity because it makes my wife happy and after how generous she has been for over the last 4 decades with her girlfriends and accommodating my many fetishes, I owe her this and will gladly stay in chastity as long as she wants me to. Plus as I get older, my sexual needs are less and erectile problems are becoming more common. Being limited to a few orgasms a year fits in well with those issues very well. No longer do I have performance anxiety or get upset because my wife does not want sex when I do. Masturbation has been no more of over a years. I actually was allowed to do it supervised for Valentine's Day. Not as good as I remember it. Much better when my wife does it.
So that is how we got into chastity. Something I thought was very stupid just over a year ago. Now I am uncomfortable if I am not locked into my Holy Trainer waiting on my Jailbird which will arrive next month. I rarely feel like cumming anymore and my wife cares more about me cumming than I do. I am addicted to the feeling I get from hours of edging and how sexually aroused I feel most of the time. I love that I can get erect from just scratching my wife's naked back of seeing her in the buff. I love the extra energy I seem to have and not having to deal with the depression and boredom that follows my orgasms. If there is one negative it is how much more difficult it is to get erect after a few months being locked up. Even Viagra is not helping much anymore. My penis still turtles when locked up. It takes a few days outside of my chastity cage for my penis to return to its normal flaccid state. I have decided that I really do not care as I really do not care if I cum again anyway.
