I suggest using the keyword "brazilian" to search the board. All the threads that will come up as research results are highly relevant to your question!

I personally won't even consider going all the way as far as waxing goes. I get a traditional bikini waxing that leaves the area where the thigh connects with the pelvis clean and trim the rest. Never had a single problem, although I must add that I've never shaved down there, just waxed, so the hair is not very strong and not prone to ingrowth.

Good luck!
