I had galvanic electrolysis done in the late 1990's after shaving and trimming most of my adult life. It took two and a half years to rid all hair from my butt crack, genitals, pubes, stomach and chest. After 22 years, I just had a 30 minute 'clean up' of hair that was dormant at the time. I've been smooth as glass for all this time and don't regret the pain I went through to get this done once and for all. I just wish I had it done in the early 1980's instead of waiting. Good luck with all your shaving, guys! BTW I've either gone commando or worn men's 100% nylon bikini briefs since the mid-70's.
I used to shave in the 70s and 80s than things got a little to hetic, and just again began to shave 2 years ago.
