PEARLING...NOT WORK SAFE

I thought I knew it all about sex...WRONG

I just heard of a procedure called pearling (aka speed bumps)...

Apparently this is done in jail a lot (by all races). It's when a pearl is placed under the foreskin of the penis. What it does is stimulate the clit during sex. Has anyone heard of this?

Pearling or genital beading is a form of body modification, the practice of permanently inserting small beads made of various materials beneath the skin of the genitals--of the labia, or of the shaft or foreskin of the penis. As well as being an aesthetic practice, this is usually intended to enhance the sexual pleasure of partners during vaginal or anal intercourse.
The practice seems to have been fairly common across world cultures and is still done today. In contemporary society pearling is usually done by professional body piercers, and sometimes by people who specialize in surgical body modification (who are rarely qualified doctors and often very publicity-shy, for fear of legal repercussions).
Pearling is very common in the military and prison systems of the former Soviet Union and Eastern Europe, as well as among Organized crime syndicates. Modification is performed by inmates using household appliances, without anesthetics; soap is used as antiseptic. Typically, insertions are made from specially prepared round plastic pieces. In average, this modification involves 3-4 round balls 6-8 mm in diameter, and several cylinders 1 cm long and 3-4 mm in diameter. An opening in the skin is made by a metal chair hitting a penis or a specially sharpened handle of a spoon, then the plastic is inserted. These modifications are called "shary" ("шары", balls) and "shpaly" ("шпалы", crossties). Pearling is also found in members of Mara Salvatrucha (MS-13) gang in Guatemala, El Salvador and Honduras. This procedure involves the piercing of the foreskin and inserting a marble, 10-15 mm in diameter. The insertion of the bead, known as "el cinco" (the marble), is done mostly in prisons by inmates without the basic hygienic conditions. Gang members use the bead as a form of gang allegiance (along with ornately decorated tattoos that depict gang life) and as a sexual enhancer.
