Diana & Actaeon

This is a rather simple myth. Basically, Juno was taking a bath and Actaeon saw him during his hunt. She turned him onto a stag and he was eaten by his own dogs. The End.

Something is confusing here, though. Juno is Diana, and Juno, in the two myths I just read, was married. Yet here it says that she's a virgin goddess. How is that possible? You can't be a virgin if you're married. The whole point of being married is to be able to have kids without people whispering behind your back, and I've known since second grad that you can't have kids if you're a virgin. So what's going on?
