Geoedward saidOk, I have to ask, what is a Prince Albert? I think I know but am not sure?
A metal ring inserted through the penis, named after Queen Victoria's husband, who supposedly had one. In those days it went through the foreskin, its alleged original purpose being to prevent the penis from bulging down the legs of the snug trousers that had become fashionable in the early 18th Century. The man wore a cord or tape around his waist, under his clothing, to which the ring was attached, holding the penis in an upright attitude. You have to understand that elasticized and fitted underwear had not yet been developed at that time. But this purported history of the PA remains speculative to my knowledge.
Most of the guys here are from the US, and are discussing the type of PA most commonly used on a circumcised penis, lacking a foreskin. This kind goes through the urethra and the frenulum, as pictured below, done for mostly cosmetic reasons and claims of increased sexual pleasure.
A disadvantage is that a urethra PA can interrupt the urine stream, making for a messy spray. Oral sex also can become problematic for the other guy, depending on the PA size. I personally don't like larger ones, the metal clanging against my fillings, and disturbing my preferred oral technique.
