If I manage to have two orgasms through vaginal penetration, then for at least a week I am kind of sure I wouldn't have a NE, and so I can go ahead with the planning of the orgasms. But after just masturbation, I have no guarantee, maybe the next night I get a NE again.
With our condition, unless you're already in some kind of a strong relationship, it is not easy to find a partner though.
