Masturbation refers to one's own sexual stimulation usually of a person's genitals, usually to the point of orgasm. Both women and men can masturbate. The stimulation can be performed manually, by other types of bodily contact (short of sexual intercourse), by use of objects or tools, or by some combination of these methods. Self masturbation is a common form of autoeroticism. Masturbation with a partner (called mutual masturbation), is also common.
