The Prince Albert (PA) is the most common male genital piercing. The name comes from the legend that, like his contemporaries, Queen Victoria's husband wore a "dressing ring" in the tip of his penis, so it could be strapped to his leg, thus eliminating that unsightly bulge in his fashionably tight trousers. Whether this is true is the subject of much debate.
The piercing consists of a ring or circular barbell which goes in the end of the urethra and exits through a hole on the underside of the penis where the glans meets the shaft. Although it may look scary initially, this piercing is actually easy to sit through, and even easier to heal since the tissue being pierced is very thin (but very strong).
