Having yourself professionally waxed, while certainly NOT pain free, is more bearable than sugar "waxing"... especially if done by somebody inexpert in their technique. I've tried both.
The professional grade waxes simply work better than sugaring. Part of this is due to the wax itself (which is not sold to the general public) and party of this is due to the skill of the waxer. Absolutely no doubt in my mind about that. They are more effective at pulling the hairs from the root while causing correspondingly less skin irritation and pain.
The best part is that every time you go, the hair regrowth gets sparser and sparser and the pain gets less and less.
For example, I *was* pretty hairy on my back. No longer. The regrowth is significantly slower, finer, and much less painful to rip than it was when I started this. I lift, and eat right, for many reasons. One of them is appearance. Heck, waxing VASTLY improves my appearance, and unlike shaving (which squares off the hair at the follicle, thus causing the regrowth to FEEL more bristly) it doesn't grow back bristly. My only regret (I sound like an infomercial) is that I waited this long.
Give a professional a try before you turn yourself off to waxing. Also, nothing says you can't take an NSAID before you go to waxing. That dulls the sensation a bit.
As for the bikini wax thang, I HEARTILY agree. Props to the grrrls for going through that torture. No problemo trimming, but I aint waxing there.
