Sex drive

More commonly referred to as 'libido', a sex drive is a desire for sexual contact. In the context of asexuality, sex drive is an important concept because some asexuals have a sex drive but lack sexual attraction, 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 don't fully understand the definition of asexuality, or don't see sex drive and sexual attraction as different things.
