This was conveyed to me by D, a dominatrix who is married to a male sub, who I shall call S. I have invented some dialog to frame her accounts as a story.

"Think of me, always," she whispered to S, as he left for work.

She knew she did not need to do this, as orgasm control was a key part to their relationship. Of course, 'control' does not automatically mean denial, but it did in their case. She liked to keep him attentive, so combined denial with acting provocatively.

D insisted on total honesty from S, and usually got it. Because of this, they could avoid the use of a chastity device, and relied on self-control. She assessed the volume of his testicles before he left for work, and again when he returned, just to be sure. if he masturbated to orgasm as work, he usually told her, due to his disgust at the act. Punishment was to miss their monthly conjugation, though D also masturbated frequently in his presence.

D had read about the suggestion that regular sperm removal was a good thing, though it seemed that there was no convincing evidence on this. In any case, rather than forced milking, she wanted a more natural way, but still avoiding a pleasurable orgasm.

Once, 3 weeks after conjugation, he had a nocturnal emission. She found a damp patch on the sheets, and discussed it with S openly.

"I noticed your nocturnal emission, S" she said. "How did it feel?"

"I feel guilty, embarrassed. I wish you didn't find it."

"What were you dreaming about?"

After a long delay, he said that he dreamt about a girl in school, who he saw getting changed for the gym.

"It is wonderful that you are so honest, S. Next time, please tell me, and, um, wash the sheets."

A few months later, the same thing happened, but S said that he was dreaming of D. She found this tremendously erotic, because it seemed like she possessed him in his sleep. In fact, she enjoyed it more than their conventional coupling, and resolved to make use of it.

After a few days of thought, she explained the new rules to S:

"Dear S, I know that you would do anything for me. I wish to remove our monthly conjugation. Instead, we will use your nocturnal emissions. They are beneficial for you, and an amazing turn-on for me.

However, once every few months is not enough. I plan to improve this, by edging you every night, just before you go to sleep. In addition, you will sleep naked, and if I awake in the night, as I sometimes do, I will edge you again, whether you are awake or not. When you have a nocturnal emission, wake me and tell me your dream. I will then edge you again, and we we will sleep."

"But I get so embarrassed, and it doesn't really feel like a proper orgasm," he responded.

"I know darling, but it has to be embarrassing, otherwise you could simply masturbate, and we don't want that do we?," said D with a smile.

"Anyway, the main reason we will do this is so that you can give me an amazing turn-on, darling. We start tonight!".

That night, she ensured he had a massive erection before sleep, and whispered

"Think of me always."
