The prostate gland is a muscular gland located at the neck of the male bladder and the beginning of the urethra. This walnut-sized gland secretes a milky, alkaline fluid that helps protect the sperm from the acidic environment in the vagina. Muscles in the prostate gland help propel semen during male orgasm.
Along with aiding sexual reproduction, the prostate gland is also a great source of sexual pleasure for many men. In fact, this gland is often referred to as the male G-spot, or P-spot. Massaging the prostate gland can often bring on more powerful and satisfying orgasms.
