Ampallang Piercing - Sailor Sid Diller (Patreon)

The Ampallang Piercing  (which comes from the Iban Dayak word pallang - crossbar) is, for want of a better word, one of the more serious penis piercings, going through the the glans (though a transurethral option is available, though far less prevalent in American piercing culture) of the penis. 

Healing is slower and more painful than many of the more common genital piercings.

I figure if you're here, you probably already know the history of the Pallang piercing, but if you want a little more context, check out the wiki page here: https://en.wikipedia.org/wiki/Ampallang 

This photo dates back to the early 1970s, and features Sailor Sid Diller performing the piercing with a piece of externally threaded jewelry.
