Weighted Average Sexual Age (WASA):

The weighted average age of a person's sexual partners.

Calculated as the sum of (Age of partner x Number of sexual intercourses with partner) for all sexual partners.

It is expected that a cool adult male's WASA be less than his age.

An adult female's WASA should be 5-10% higher than her age.
Wade's Weighted Average Sexual Age is massive....over 30! He loves his MILFs.
