Unless someone could somehow perhaps discover or invent a way to achieve orgasm without masturbating (though in fairness I should say that it definitely won't be me).
Have you heard of the John C. Lilly experiments on monkeys?
"It was found that in male monkeys there were separate systems for erection, for ejaculation, and for orgasm. With an electrode in the separate orgasm system, the monkey would stimulate this region and go through a total orgasm without erection and without ejaculation. Given the apparatus by which he could stimulate himself once every three minutes for twenty-four hours a day, the monkey stimulated the site and had orgasms every three minutes for sixteen hours and then slept eight hours and started again the next day.
In the negative systems it was found that, if the apparatus was set up to automatically stimulate the monkey once every three minutes for twenty-four hours a day, it would shut off the stimulus each time during the -twenty-four hours. If this stimulus was continued for too many hours, the monkey became sicker and sicker; finally unable to push the switch, it headed toward its own death. This clinical picture could be changed by allowing the monkey to stimulate the positive systems which completely reversed the "dying" syndrome."
