hood peircings do not affect the clit. they cane be very stimulating. a vertical peircing with a small barbell rocks. the bottom ball of the barbell rests on the clit under the hood. the top ball is outside and visible. you can use the top ball kinda like a little joy stick. my wife has one, i speak from experience. touch a vibrater to that top ball, it sends those vibs straight to the clit.
try this out for some ideas:
