This has hardly to do with proper "sex" but once a friend of mine heated a car key with his lighter in front of my eyes, and he put the incandescent key on the back of my right hand, and I, knowing that the key was fu*king hot, did not move a muscle, and actually quite enjoyed the pain (branding style)...the only drawback was that for a year and a half I had this key-like mark on my right hand. hard to explain to my parents, too.
