Masturbation refers to sexual stimulation, especially of one's own genitals (self masturbation), often to the point of orgasm.^[1] 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.^[2] Masturbation is a common form of autoeroticism, and the two words are often used as synonyms, although masturbation with a partner (mutual masturbation) is also common. Animal masturbation has been observed in many species, both in the wild and in captivity.....ok too much information!
