Chastity in vanilla life discussion

This is a bit of a long one so apologies if I go off on a tangent, but please give me your advice! I guess I’ve always been drawn to the idea of surrendering control, but what really shifted things was getting a Parkinson’s diagnosis while still relatively young…this basically brought about these symptoms (besides the usual weakness etc); …A fixation with sex and a growing interest in porn …Difficulty actually performing intercourse …meaning I can no longer maintain an erection without Viagra …Growing suspicion that my partner was cheating earlier this year…based on my obsession with IT data sets, Google history, location tracking and other “perceived behavioral shifts” Basically, we reached a point where I was following her around, making her life difficult, and doubting her. She is honest, very positive, trustworthy person who knows right from wrong and wouldn’t cheat. What set this off was the accidental discovery that she had cheated when she was with her first long-term boyfriend at university…but never told me in our 15 years together. She feels ashamed and keeps it private about it. I started worrying because a previous partner of mine also cheated. Last year, I suggested chastity, and while she was repulsed by the concept, she reluctantly agreed to hold the keys, “as long as she didn’t have to do much”. This setup was destined for failure from day one, and it did fail! Matters came to a head very recently and I will leave unless something changes drastically…specifically my behavior. I suggested wearing the chastity device for 2 weeks because I felt so different and in control when I had it on! …she could just hide the keys and not have to do or say anything else, and I wouldn’t bring it up again. She said, “ok, whatever”, and hid them. So, I ask everyone, what now? I love transferring power; I love wanting to please her constantly. But what comes next? Eventually, I would like to be teased, to become a good boy without the kinkiness, and to change my behavior! Thanks very much in advance. …
