My wife also decides when I will orgasm and decides if there is any sex. It has improved our marriage. We are more intimate, I am a better listener, and I am more focused on pleasing her.
I assume you are pleased that your wife has taken control of your orgasms and initiates the sex? Many married submissive men want that.
As part of our written agreement which includes milking,finances,etc. Mistress or a person of her choosing milks me twice a month unless she finds fault with me. This is always done when I am restrained and then I am relocated.
Our arrangement lets me masturbate once a week unless my Wife decides otherwise. She postpones my masturbation about half the time, usually for a good reason, but I rarely go more than 2 weeks between orgasms.
She doesn’t really “supervise” me but I’ll have a designated time to myself (like 20 minutes +/-) in my bedroom and she often texts me selfies in sexy outfits or lingerie and I’m allowed to use those to get aroused. I’m definitely not to use any other photos or videos.
She had me install a toilet paper holder in my room for my wanking.
