Dumbledore the Bear?

Not sure how this answers the question, but when the author of the mega-gazillion-selling Harry Potter Inc. series fielded an audience query about whether or not headmaster character Albus Dumbledore ever finds true love, she replied, "Dumbledore is gay."

Ummmm, yeah. Purportedly when asked if Hermoine ever bears Harry's children, the author quipped, "Hermoine is barren."

J/K (Rowling) about that last part.
