Stinging.......once upon a blue moon whenst backpacking in Sri Lanka where they use cinnamon oil instead of deet as mosquito repellent, works very well, the friend I was travelling with doused himself in that there cinnamon oil, went to have a leak without washing his hands.......and for the next 30 minutes was in the shower with a soaking wet towel wrapped best possible around and in-between the pearly bits, emitting strange noises, real loud like and wondering in a high pitched tone if he would ever be able to reproduce again........, ah, and the shower was outside the bungalow, not too far from the restaurant, certainly within earshot as others testified later.....Oh well
