When you tell him
First thing you need to know is that domination and sexual denial are very linked. The first task is to make sure your boyfriend give you absolute power on his orgasm.
So, in order to motivate your boy, you're gonna say to him that you will fulfill his wildest fantasy (it's anal, tell him he is gonna fuck your ass; it's blowjob, you'll eat his cum ; creampie; latex...). Every man has a strong fantasy. Find his.
Then, tell him he has to be trained to give up the control of ejaculation to you so you can have an orgasm too during that fantasy you're talking about.
after that the training begin. Tell him he has 1 minute to cum (take a timer). Till he hasn't get to cum in one minute he cannot fulfill his dream. Try that test every two days. Put some dirty lingerie to help him.
Once he has cummed it in one minute, go to the "30 seconds test" and tell him that the objective is to cum in ten seconds and that you know he can do it. So do the same training with 30 seconds. But this time to help him concentrate tell him he has to ejaculate only during those sessions. (that denial time might be bad for you; but YOU can masturbate). Be a real bitch during those sessions to help him making it in 30 seconds.
If he fails to do it within 1 week (witch is very likely to happen), ask him if he has cummed out of your sessions. Search his internet-search history to find if he has watched some porn, try to find any proof that he has been masturbating.
Once you have found a proof, he has been masturbating; you'll have a talk with him saying he is not trust-worthy so you have bought a CHASTITY DEVICE so he cannot trick you again.
It might take a long time to get him to cum in 30 seconds so you might tight his hands in his back and use your two hands very fast so he cums but always stop immediately when 30 seconds are done.
