What I do is start running the bath water on medium temperature and while it's warming up I get myself aroused. Then, I get in and put my butt against the wall of the tub under the faucet and lift my clit as high as I can while holding my lips open. I let the water run and within minutes I get the best orgasm! For an even better one, when you're about to come pull away and relax your muscles. Do that a few times and when you finally come it's AMAZING.
