Masturbation

These are often solitary stroking (often by back and forth, friction, pressure…) at the level of the genitals (penis of the boy, vagina, vulva, clitoris and breasts of the girl) that give pleasure or an orgasm.

Masturbation can be accompanied by ejaculation after puberty for boys and secretions for girls.
The stroking can be accompanied by images or erotic scenes displayed in the mind.
