Terminology
While masturbation is the formal word for this practice, many other expressions are in common use. Terms such as playing with yourself, pleasuring oneself and slang such as wanking and jerking off are common. Self-abuse and self-pollution were common in early modern times and are still found in modern dictionaries. A large variety of other euphemisms and dysphemisms exist which describe masturbation. For a list of terms, see the entry for masturbate in Wikisaurus.
