In fairness, a great deal of older fairy tales are about sex. Rumpelstiltskin is a warning of the dangers of female masturbation, I think, and in a few versions he jumps up her grand canyon into her uterus when she gets his name right. I seem to remember early Cinderella-type stories where the prince is searching for the owner of a fur slipper, not glass - anyone who claims there's nothing euphemistic about a fur slipper needs their head seeing to. Sleeping Beauty also didn't always get woken up by the prince's kiss - in fact, she didn't get woken up when he had his way with her limp form, either. Many of those Disney princesses were still kiddies when they got married - Prince Charming often has paedophilic tendencies, hooking up with girls as young as seven. A little boy on the cusp of change (puberty?) whose wood grows when he gets upset (the lying was a more recent modification, though lying was a common trigger for the aforementioned stress) just smacks of repressed sexuality, though I'm not too sure about Gepetto being a paedophile - I've never heard any versions with anything to indicate that.
