Honestly I dislike the idea of being denied orgasms for the sake of it. But I would like to do it as part of a larger bdsm relationship.
My husband and I aren't huge fans either, but he loves to be told when and how he'll cum. I think it's a nice variation on the theme. The sub is still handing over control, but they get to enjoy all of the bliss of orgasm and the dom/me gets to enjoy watching their sub get something they like.
