ART thalpotentiginy

Yeah, that's a new word for me too. I must say, that the folks over at Daily Deviant generally manage to make me feel like the most sheltered, vanilla thang on the whole interwebs.

Thalpotentiginy means arousal by warmth or heat. Honestly, is there anything out there that DOESN'T make someone hard?
