The question of Lord Voldemort’s sex life is a horrifying one, regardless of the context. But yes, someone really did ask J. K. Rowling about his virginity.
@michaeljtabb Does a dehumanised wizard killer who murders in the pursuit of his own immortality forfeit the right to ALL privacy, Michael?

Did Voldemort have time to lose his virginity while he was busy securing immortality? That query was posted originally on Quora, then caused quite the stir on Slate. One fan even dared to ask J.K. Rowling herself if He-Who-Must-Not-Be-Named ever got his parsel tongued, and Rowling answered in typical classy fashion.
If you too lie awake at night pondering this question, there’s a debate currently happening on Twitter.
