The male g-spot vibrator is a specially curved device (like a skier about to take off) with a round head which is inserted into the anal canal of the male, and stimulates the prostate gland - also known as the male g-spot - this way, normally producing a host of different, and quite intense sexual sensations. It also stimulates the perineum. The device is hands free, and is controlled with the sphincter muscles. It is also known as a 'Nexus massage'. Prostate massage is also used for health purposes, as recommended by a health professional.
