I shave as many areas that I can. The boob area, stomach, underarms are a must (doing that for several years), the legs I have been shaving for the last two years at least, starting with every month or two to lately every couple of days. I don't know if it should be done that often, but they are so smooth now. Pubic area, of course, also. Was thinking of buying a waxing kit and getting rid of the hair for a month or more.
