This was a case of deliberate premature ejaculation, not masturbation.
Or was it a case of withdrawal-- a form of birthcontrol (albeit a not very effective one), ie, malthusiamism?

And I am not sure that if you lie down with a woman, get excited-- and then finish up with out her--isn't that a sort of masturbation? We had a president who would most likely define that at not having "sex"-- ("Sure, i went to bed with her, and sure I became aroused-- and yes, i even climaxed-- but not in her-- she never got a chance to get aroused-- she never climaxed.. So, no, I never had sex with her! )(and well, in this day and age a very dangerous activity!)(followed up, by our former illustrious leader, with little game played with a cigar--proving that sometime a cigar isn't just a smoke!)
