I made myself masturbate in unconventional ways until it made me cum. Well, it kept things interesting and prevented me from being able to cum for three days. Yes, I look a bit silly for some of this, but that's part of the fun.
I put this rule in place on Friday. All day Saturday I couldn't cum, but today my balls needed release so badly, that it inevitably happened. It's a pretty hot ejaculation too. Felt amazing.
