well, first shave it downwards with the grain to make the hair shorter and minimize it making a rash
by pulling the hair when u actually shave. Use ALOT of shave gel, or put soap on a sponge and rub it till its foamy, apply the soap on the area, and rub it with ur hand, itl make a thick cream just like shave gel. then shave sideways, right to left and then left to right going VERY slowly, your trying to not pull the hairs. then shave up, and then diagonaly. it might rash but after a few weeks the rashing will go down alot, always keep it shaved and dont let it grow back. put on lotion when you get out of the shower.
