Yes. Now I tend to be more into forced orgasms. So if I task my submissive to masterbate to orgasm a certain number of times and they fail to do so, I put them on a regimen of masterbation with cum restriction. It usually doesn't take more than a day or two and I rarely have to repeat the lesson.

My primary use for cum restriction is to "prime the pump" so to speak. So if we have a rendezvous planned, I also put her on cock restriction a few weeks before a meeting and on cum restriction 4-5 days before the meeting so that she's very horny and primed for me.
