I didn't know that was the word for it, but I realised it had something to do with the sense of smell. My goodness, I LOVE smelling a man's hairy armpits. That MUSKY ODOUR!
Olfactophiia ( being turned on by odours, especially body odours is a massive part of group sex. You have the smell of sweet, cum, just fucked holes, maybe even piss. I knew 2 ladies (who unfortunately have passed) who had a small private dungeon space in their house. Entering that room was heaven. You could smell the sweat, cunt, piss, fear, cum, smoke, leather, pvc.....a special place!
