Male Orgasm Questions

[Gentle]

Ok, this is just something that I'm kind of curious about, random as it may seem.
I have noticed a lot of Dominants get on and discuss, teaching their female subs how to orgasm on command, or brag about their subs accomplishments in that arena. (That's terribly cute by the way ) but I haven't found anything about any dominants doing that to male subs.

I was searching online and I found websites where there are techniques for men to control their orgasms so they don't ejaculate, and websites on how men can achieve mutliple orgasms. And of course there are cock rings and devices that limit or prevent a man from orgasming, but I'm not really concerned with whether or not ejaculation is a result, simply the programming to make him cum at your will.

So the question is... is it possible to do so? Has anybody here ever tried?
