When I had long hair (I still miss it!) it would be a quick tool to use. Since I have very sensitive skin just leaving it down could be ticklish when it brushed against my arms or neck. Most of the time it would get annoying because it wasn't the normal responce more of just a tingle down the spine that would make me shiver. But honestly using hair by lightly brushing it over someone's skin can get some great responces. It just sucks when the ler realizes that and turns your own hair against you.
