Shaving + grease works great, depending on the quality of the grease. When I was an 18thC re-enactor I portrayed a Cherokee (we were short on real Indians and they asked me to join them if I would do it right - I did, both) and they shaved or plucked out all body hair and only kept a scalplock on their heads. You just can't fake it because when you paint up for war with bear grease mixed with pigments, even a small amount of body hair makes you look like a young porcupine. Anyway, while shaving I couldn't seem to find a good stopping place at the crotch so I just shaved all over (I had a very good stick/glue-on scalplock). I found the crotch shaving idea miserable in everyday clothing because everything stuck to everything it touched, until I realized that the Cherokee rubbed bear grease all over their bodies. Stuff lasts until you wash it off either by hard scrubbing or soap and water. I wore the proper loincloth which was 6' long but only 9-10" wide (you learn how to tuck it to keep from visually tea-bag people), and even though they're made of stiff, heavy wool they are comfortable. Bear grease can be found on the Net or through re-enactment forums as some states allow it to be sold, and it was pretty much the WD-40 of the eastern tribes. Can't beat it for gun grease, my Bess was "in the white" and it never, ever rusted. Felt sorry for the authentic Brits who had to scrub their barrels with brick dust every day to keep them bright.
Now, that's probably more than you wanted to know about backwoods 18thC America, and about me.
