Hey Heather, I've used Nair before. It was pretty thick so it didn't run, but the smell wasn't great lol! Also, because the hair there is so thick, it takes a while to get it off properly - I found I had to shave after anyway (that may just be me though...). Also, because that's a sensitive area it may get a little 'burny' after a while. Personally I prefer just shaving
