I dont think your question is odd just because it's not something that's frequently asked. :)
I shave this area regularly. I've been waxed, too. Waxing leaves you smoother, but does hurt a bit and be too costly to maintain if you're on a tight budget. You also have to let the hair grow back in a bit before you can wax again.
The trick to shaving is to take your time. If you're trying to squeeze it in while you hop in the shower for 10-15 minutes, you're going to have bumps and possibly nick yourself. This sounds weird, but I get much cleaner results if I soak in the tub first. The warm water helps relax the skin and open pores, also will soften the hair.
ALWAYS ALWAYS ALWAYS use a moisturizing shaving gel or cream. Don't use soap if you can help it. apply the gel/cream and let it sit on the area for a minute or two, then shave. I've always been told to shave in the direction that the hair is growing - I do that but often find that it doesnt get it all and I have to go back over the area in another direction (use a small amount of shaving cream). dont go over the same spot more than 2-3 times or you might get razor burn (been there, done that....)
Also use a NEW razor blade - dont shave your legs and underarms first because that will dull the blade. Take your time with it, especially at first so you dont nick yourself.
Also, you might want to heavily moisturize the area after shaving. I like to use a thick lotion that absorbs fast, like Gold Bond Healing. keeps the area soft and smooth.
good luck and happy shaving!
