you go to a professional would be my take...I was looking around the net last night...boy there're a lot of sites about hair removal. From what I can see all of the non-permanent options have ongoing costs, ongoing time commitment and ongoing risks of error/infection. Laser seems popular, all sorts of marketing blurb about it, but really because it's easier to do. However it doesn't work on all hair types and hair can grow back. So electrolysis seems to still be acknowledged as the only permanent option though even then the claims are 'hedged'.
You know what it's like, you go looking for info on cyclists shaving their legs and you end up on a trans gender advice site

reading about how, if you have the money etc, then electrolysis is the best way. A lot of clinics seem to be pushing the fact that they have experience working with men, so there must be some demand out there.
It would appear that full, and permanent, depilation below the head is increasingly popular for 'regular' guys as well. Lots of reasons I could have worked out myself, athletes, swimmers particularly and bodybuilders. Then there's the stuff that wouldn't have occurred to me, pure vanity, aesthetics, better for tattoos, resolving ongoing problems with ingrowing hairs and just because they like the feel.
Where do you stop? - well if I were a swimmer/bodybuilder then it would need to be no limits. Can you imagine having a hairless bod with a hairy bum? but I reckon that would be dedication, I imagine the pain factor is a little higher in certain areas.
On a totally serious note I'm now considering some electrolysis attention for the hairs that grow out of my ears. Much as I really enjoy shaving/trimming my ears I'd quite happily spend a few quid not to need to anymore.
Now what about my ever increasing gorilla back?
