In the 18th and 19th centuries, some European theologians and physicians described it as "heinous", "deplorable", and "hideous", but during the 20th century these taboos generally declined.There has been an increase in discussion and portrayal of masturbation in art, popular music, television, films, and literature.This technique may include the use of a simulacrum, or artificial vagina.There are many other variations on male masturbation techniques.Masturbation involves touching, pressing, rubbing or massaging a person's genital area, either with the fingers or against an object such as a pillow; inserting fingers or an object into the vagina or anus (see anal masturbation); and stimulating the penis or vulva with an electric vibrator, which may also be inserted into the vagina or anus.It may also involve touching, rubbing, or pinching the nipples or other erogenous zones while masturbating.This technique may also be used by some circumcised men who have sufficient excess skin remaining from their circumcision.
Mutual masturbation (mutual manual stimulation of the genitals between partners) can be a substitute for sexual penetration.
The outer foreskin glides smoothly over the inner foreskin.
The glans itself may widen and lengthen as the stimulation continues, becoming slightly darker in colour, while the gliding action of the foreskin reduces friction.
The English word masturbation was introduced in the 18th century, based on the Latin verb masturbari, alongside the more technical and slightly earlier onanism. Suggested derivations include an unattested word for penis, *mazdo, cognate with Greek mézea μέζεα, "genitals", or alternatively a corruption of an unattested *manusturpare ("to defile with the hand"), by association with turbare "to disturb".
were common in early modern times and are still found in modern dictionaries.The most common masturbation technique among males is to hold the penis with a loose fist and then to move the hand up and down the shaft.
