Once again, we are sincerely grateful to John Lopez for his help compiling this information.
A PA wand is a sexual toy. They are worn only for short periods of time to stimulate the urethra as well as the eyes (they a sight to behold). Most people who use wands are turned on by inserting objects into their urethra, but anyone can have fun with a wand if it's the correct size and shape.
In order the wear one, the penis must be pierced. A Prince Albert piercing is most common, but they can be worn with Apadravyas and if an Ampallang is pierced through the urethra, it will work there also. For these it would require two posts instead of just one.
The wand is inserted using a petroleum based lubricant such as Vaseline, A&D ointment, Triple Antibiotic, Bacitracin, Neosporin, etc. Water based lubricants like K-Y jelly can absorb into the urethra and leave the wand stuck inside...which can damage the tissue when it's removed.
Wands can be any length, from 2 inches to 6 inches, or even longer. The thickness is determined by the wearer, it needs to be comfortable. The wand's shaft can be hollow or solid, made of steel, titanium, or even nylon and surgical plastics. Hollow shafts make ejaculation and urination possible without having to remove it.
Measurements need to be exact and made while the penis is completely erect. This is the hardest part (no pun intended).
