My biggest kink is to let my genitals be bitten by mosquitoes and biting flies. I find the feeling to be very erotic and often let them feast on me for hours at a time and i enjoy every bite and jab. I cover all the rest of my body so this is the only exposed flesh. It takes 3 days for the area to heal after and there is no scarring or visible signs afterwards.
I find traveling to northern areas of Canada are the best, but northern Sweden is also wonderful. The bugs up North do not carry the nasty viruses you see in warmer climates. West Nile is not seen further North either.
Anyone else ever try this? It has it's own name of Entomophilia.
