In order to adequately engage in perineal massage, women or their partners should begin by inserting their lubricated thumbs and index fingers about two inches into the vagina and apply pressure. Experts recommend applying pressure downward for two minutes first, and then sideways for two minutes in each direction. Under no circumstances should women use any other object other than a pair of clean hands.
