I am looking for small pins to place in my wife's labia/breasts... Any ideas on where to look for these? I am not looking to go through under the skin from one area to another. I am looking to stick very short needles into them directly from top down. Also, what gauge? I've read 22 is a good place to start.

Also, are there are reasonably priced shock sticks that could be used on those same parts? Thanks.
