Female led relationships discussion

I keep my husband in long-term chastity. I have been milking him about once a month. I do this with a prostate massage while his chastity device is on, so there is no erection and no orgasm. He dribbles out his cum then licks it up. So, a question for the guys in long-term chastity or for their Owners. If I stop the milkings, will his cum just dribble out at night as needed during wet dreams? He stays locked overnight so he won’t be able to have an erection. If you have experience with this, please share. Thank you, all my new friends in the community. I love reading your posts and sharing My wisdom when I think it helps.
