When you feel that your life depends on it, probably. "If Chaac doesn't get his sacrifice, it won't rain and we'll all die."

The Mayan civilization crashed, burned and depopulated long before the Conquistidores showed up.

A persistent Bermuda High off the coast served to stop rainfall in the Yucatan for a couple of hundred years.

Guess that "ritual mutilation" didn't do much good then.

I can think of lotsa better things to do with my genitals; all including my wife ;-)

The rituals failed. Their civilization failed. In the end they owe their biological survival and any memory of their former glory to the arrival of the Spanish.
