Odaxelagnia: the paraphilia involving sexual attraction to biting or being bitten.
Biting is one of my favourites, it is impossibly intimate and can range from gently pleasant to terribly painful… yummy! I did not know there was a term for it!
Sadly the reference to odaxelagnia was removed from Wikipedia with the concern that it is a “Non-notable fetish”.
See, and people say sex blogs aren’t educational!
