Not really interested in chastity play, but love orgasm control, and I think there's some overlap in the effects. With orgasm control, mistress does tend to allow me to cum less often than I would under my own recognizance, so there's a bit of the "he's more submissive when he doesn't cum" impact, although I only go 7-10 days versus what most chastity players do. I also know I only cum with her permission and whims, so I find myself VERY highly motivated to please her all the time. And lastly, when she does let me cum, I find myself incredibly grateful to her, I mean overwhelmingly grateful, which is like another motivator for appreciation and obedience
