In the Andean world view, the beings that inhabit the different worlds interact and participate in sexual relations.
The dead are shown as sexually active beings, interacting with each other and with living people. The dead participate in sexual activities that are non-procreative, such as masturbation.
The objective of these activities is not procreation, but rather the release of semen, the fertilizing fluid that must then be offered to the earth, which is where the dead dwell.
