Styles & kinds of Body Piercing
Bridge piercing
A bridge piercing passes horizontally through the fleshy part between the eyes above or at nose level (a vertical bridge piercing is a surface piercing and technically quite different). The piercing is best done with a straight, curved (this will sit crookedly unless it's a flush fit), or staple barbell, unless it's being done shallower to allow the wearing of a smaller ring.
Is a piercing performed through the surface skin of the shaft of the penis just under the glans, but not entering the urethra or the shaft core. The piercing is done across (transversely) to the shaft, but the term is sometime extended (incorrectly) to include piercings running longitudinally (parallel to the length of the shaft) elsewhere on the penis.
Industrial piercing.
An industrial piercing is two or more piercings connected by a single barbell. In normal usage it refers to an ear piercing whereby two helix piercings are connected by a single straight (or curved) barbell.
Labret piercing.
The Labret is a piercing through the lower lip.
Prince Albert Piercing
Is one of the most common male genital piercings. It heals quickly and is relatively trouble-free. Many men also find it to be one of the least painful male genital piercings, although pain is subjective — some men report some degree of pain, while others compare it to a light pinch or feel hardly anything at all).
Tongue piercing
Is one of the most common, popular, and easy-to-heal piercings out there.

Is a transparent, glassy thermoplastic, a revolutionary plastic at the time, it had both low density and was stronger than previous plastics, as well as having excellent water and UV resistance.
Is a technique used to modify the surface of a metal, in this case for body piercing jewelry. It may provide greater corrosion resistance, create a different surface topography, and change the crystal structure close to the metal surface of the body jewelry. The process derives its name from the fact that the part to be treated forms the anode portion of an electrical circuit in this electrolytic process.
A captive bead ring (CBR) (also ball closure ring or less frequently captive ball ring) is a common example of body piercing jewelry.
Is an elemental metal, often used to make colored body jewelry since not only is it totally hypo-allergenic, it can easily be annealed. Niobium jewelry is slightly heavier than surgical steel and is much heavier than titanium. Niobium and titanium are the only two metals used in body modification that can be anodized.
Is an extremely inert plastic, and is resistant to body chemicals. It is suitable for autoclaving, so it can safely be used in fresh piercings. Along with silicone, PTFE has become the material of choice for implant artists. One of PTFE's features is that it has the lowest coefficient of friction of any known solid material. PTFE is also flexible, allowing it to move slightly with the body when used in piercings.
The term is primarily a marketing term, and does not refer to one type (or grade) of steel. In fact, your cutlery at home and your fancy stainless steel watch are both likely to be of the same quality as "surgical stainless steel."
Implants and equipment that are put under pressure (bone fixation screws, prostheses, body piercing jewelry) are made out of austenitic steel, often 316L and 316LVM, because it is less brittle and far more corrosion-resistant.
Is a light elemental metal similar to niobium in its properties regarding body jewelry. Note that the titanium used in body jewelry is often an alloy containing some aluminum, vanadium, and/or niobium.
