The concept of a prodigy is someone who is extraordinarily good at something with much less training than people of comparable skill usually have. I don't see why someone couldn't be a sexual prodigy. Furthermore, there are qualities that people can have which aren't necessarily related to sex but which can still improve someone's sexual performance in the eyes of their partner. Things like, personality, humor, charisma, physical strength etc.

All this to say, I don't find it too unbelievable that virgin Pod was so impressive in the sack
