The idea of orgasm control or denial strikes fears in novice submissives. "What do you mean give over my ability to orgasm whenever I want?" Sure you could think of it that way, but in terms of your submission it could mean so much more. Let me start with the basic definitions.
When a Dominant takes over the right to a submissive's orgasms. This can be from not allowing the submissive to come without permission to requiring that all orgasms be given by the Dominant. Many other variations also exist.
This is much like a game to some Dominants. An activity where a submissive is brought to the brink of orgasm and then denied the permission to orgasm. Many times this also means the cessation of contact. It can be done occasionally during play or be a long term modification to that submissive's rules.
The truth is that not all Dominants enjoy controlling a submissive's orgasms and it is more likely seen in Female Dominant relationships. I don't know the reason for this, nor do I have any statistics but only what I've seen and read. My Master is more into control than denial. He likes to know when I'm nearing orgasm. It's a power and pleasure thing.
An interesting training option for orgasm control is Come on Command training. It's a form of hypnotic suggestion that can and does work. Then the Dominant totally owns your orgasms because you can't control them yourself. A trigger word, phrase or touch sets it off.
When it comes to your submission, offering over your sexuality in this way can be very humbling. An orgasm can be a lot of things to people. It can be stress relief, pleasure, connection or even just private time. Giving over your orgasms to someone else to control is part of ultimate surrender.
What are your thoughts on orgasm control? Is it something that is a part of your relationship?
