Libido
From AVENwiki
More commonly referred to as libido, a sex drive is a desire to feel sexual pleasure.
In the context of asexuality, sex drive is an important concept because some asexuals have a libido but lack sexual attraction - an undirected sex drive - while others have little or no sex drive. This is the main reason some asexuals masturbate and some do not, and can confuse people who either do not fully understand the definition of asexuality, or do not see sex drive and sexual attraction as different things.
