I also shave the sides and leave a strip, but keep the lower half completely bald for hygiene reasons. If you do shave on a daily basis and are prone to razor burn and bumps, I highly suggest using a mens shaving cream. I dont know why this hasnt hit me before, but the mens stuff really pays attention to the razor burn; i guess because men have to shave everyday and need to worry about bumps since its on their face!! LOL!
Just a little suggestion from a fellow shaver
Good luck and have fun with it!
