This has been in my post ideas folder since 2017. It comes from the blog A Dominant Wife.
Dear Miss Jay,
I have been married for three years and have “led” our marriage since our honeymoon when I first took my husband over my knee on the second night. My husband is very obedient, trustworthy and understands that, in our marriage, his sexuality is entirely subordinate to mine. I am not a big fan of penetrative sex so he has only been allowed to enter me twice since we married. I allow him to masturbate, in the bathroom, once a month which seems to me to be more than enough.
Recently I have noticed he is becoming erect and, worse, “dribbling” and even having nocturnal emissions. I am quite sure this has effected his behavior despite knowing he derives no pleasure from these lapses. They still represent unconscious disobedience and I would like to nip this in the bud. The whole point of having a chaste husband is to ensure that what pleasure he gets depends completely on my assessment of his performance in his marital duties.
I read your blog and know that you keep your husband in a cock cage. I have thought of putting my husband in such a device but I wondered if the fact his cock is in a cage might not be making too much of his male member. Drawing attention as it were. What are your thoughts?

I am just drop-jawed. So two people that have little interest in PIV sex marry one another. Of course, the letter might be a hoax.

I suspect the latter but to each their own, yes? Sure hate to think all those Penthouse letters I enjoyed in my misspent youth were frauds! Say it ain’t so, ‘Bogey?
The fantasy of denied sex is fine, as long as you do get to have sex. Otherwise, I don’t get it either.
Yeah, I don’t get it. I can see briefly delaying sex to make it all the more exciting. I can see briefly denying orgasm that makes it more exciting for women. I can’t see letting your husband jack off in the bath once a month and thinking maybe that’s too much.
I too do not get the sex denial thing. Also wonder what she looks like. I’m imaging her as ugly and overweight, someone no regular would take notice of.
