Prostate massage is one of the sexual techniques designed to stimulate the prostate gland, increase sexual sensation and assist in the treatment of prostate diseases. Prostate massage can be external as well as internal. External involves stimulation of the perineal area between the scrotum and anus, which is in the cast of the prostate gland. This technique is used to achieve an erection. Internal prostate massage, on the other hand, can be both a sexual technique and a method used for diagnostic purposes and to aid in the treatment of prostate disorders. It can be made by hand or with a vibrator.
