You and your partner could try oral sex. Your partner's tongue will not use too much pressure, and it will be wet while performing oral sex so this will provide a lubrication of some sort. Try it, and have fun! (You won't be sorry!!)
there are other ways of having an orgasm than thru your clitoris... have your partner go deeper and see if that stimulates anything like maybe finding your g spot or also be on top and sometimes riding can stimulate your clitoris enough to have an orgasm without it coming into so much contact that it is unconfortable to u
