I used to go many months between orgasms for the last 11 years and now it is only ruined Orgasms. I an tell you what my wire did.
1. As with you, no touching her of naught bits.
2. Could not see her naked. During sex I wore a hood that covered my eyes. She got into CBT and nipple torture because my moans of pain turn her on.
3. During sex my hands were handcuffed or otherwise bounds so that I could not touch her.
4, Next came the noise cancelling headphones so I could not see, touch or hear her.
4. She only used a vibrator and never me for an orgasm. I have not penetrated her in over a decade and performed oral about 3 times
5. We went a step further and I was in another room listening to her orgasm in her bedroom for a few months.
6. After a few years of this she allowed me to see and touch her only during sex because each year we decided on what to do in the coming new year and I needed to see and touch her, but only during sex.
7. She wanted me to moan more so she got some very painful nipple clips and a ball clip that she can adjust the tightness to.
8. This year she had me buy Viagra and I have to take it before sex. I am either locked or not depending on her mood. If unlocked she teases me until I get erect, waits until it goes down and repeats.
9. Now I only get ruined orgasm where before got about 3-4 full orgasms a year.
We try to mix it up each year to keep it fresh, try new things and discard the things that no longer excite us. I am I a unique situation with my key holder wife. She is bi with a strong preference for sex with women as is my ex fiancé and ex girlfriend of 30 years. Bi girls love me for some reason. I think it is because they feel safe with me since I am very liberal about sex and sexuality. Heck, I lost my virginity to a gay male friend. My wife's theory is that one a woman has sex with me, they are turned off of men. Maybe she is right.
My point is that for us chastity is not about control. It is about finding a solution to our situation.
