Although there has been increasing interest in asexuality during the past decade, still little is known on this topic. Three different approaches have been proposed, to define asexuality: a definition that is based on sexual attraction, one on sexual behavior, one on self-identification. Depending on the definition used, reported prevalence rates range from .7% to 6.1% of a U.S. sample. Many authors suggests that asexuality can be better understood as a sexual orientation, distinguishing from sexual dysfunction, as hypoactive sexual desire disorder. Socially, asexuality attracted denial and resistance due to incompatibility with heteronormative societal expectations; asexual individuals may face the same social stigma experienced by other sexual minorities. This article explore the characteristics of asexuality, hypotheses on the psychophysiological etiology and review biological, psychological, and social factors associated with asexuality.
