Autoeroticism
8
Sexual expression can occur with or without a partner or partners. Autoeroticism is the sexual activities that involve only the self. Autoeroticism is an intrapersonal activity rather than an interpersonal one. It includes sexual fantasies, erotic dreams, and self-masturbation.<br /><br /> Autoeroticism is one of our earliest expressions of sexual stirrings. It is also one that traditionally has been condemned in our society. By condemning it, however, our culture sets the stage for the development of deeply negative and inhibitory attitudes toward sexuality.
