Cayenne will fire your skin up cherry red. Just use a teaspoon in a wash rag tied with a string or rubber band and put in the bath water. Keep the cayenne in a rag, because i you don't, the little granuals will not feel good on your butt as you set on them in the bath. First timers that do this may have a butt as red as a fire engine as they run around the house tring to cool off (keep your video handy).
That is the cheapest way to use cayenne on the human body, keep out of your eyes. Shulze reccomends you use vassiline to cover up the tender parts!!!!
