"Has Jesus Ever Masturbated?"

I'm no theologian, but no, Of Course Not.

And neither has your father or your grandfather.  In fact, the only time they've ever used their hands to touch their weiners was to position it to take a piss or to scratch it.  Even in the shower, they refrain from soaping up "down there" except with a washcloth.

Only you have been "guilty" of masturbating.  Hence, your asking this perverted question.
