Pearling (body modification)

In the Visayas, pins made of gold, ivory, or brass were inserted in young boys through their penis heads, according to research by the pre-eminent historian of pre-colonial Philippines, William Henry Scott.

As the boys grew older, these pins would be decorated and they would later fasten bluntly spiked rings for the stimulation of their sex partners.

In Barangay, his study of 16th century Philippine ethnography, Scott wrote, "these ornaments required manipulation by the woman herself to insert and could not be withdrawn until the male organ was completely relaxed.

[6] The practice comes from Pre-colonial period in the Philippines wherein instruments such as the Tudruck (Penis-pin) and Sakra (Penis-ring), often made up of gold or ivory, were inserted to the penises of young adults.

wrote about this practice in his journals: Both young and old males pierce their penises with a gold or tin rod the size of a goose quill.

When a man wishes to have intercourse with a woman, she takes his penis not in the normal way, but gently introduces first the top spur and then the bottom one into her vagina.
