The prostate is sometimes referred to as the "male G-spot". Some men can achieve orgasm through stimulation of the prostate gland. Prostate dildos are similar to vaginal dildos, but they tend to be more curved, slimmer and with a softer texture. Some of the new prostate dildos on the market are driven by batteries and offer vibration at the tip; the speed or intensity of which may be changed depending on your personal preference.
