I just bought a brand new One Touch Personal Electroysis Pen, and this is my goal. I want to get the hair on my dick, nuts and my ass area. Are there any tips you can give to a newcomer on personal Electroysis with this machine? I've read around a little and googled it, some say it scars, some say its no good, some love it. Has anyone else been working on the area that I want to do? Thanks.
