Intercourse is the physical act (sexual activity) whereas eroticism is the virtual representation of the same. Eroticism is any portrayal of sex that stops short of physical contact. Eroticism is a male perspective on sex. Alfred Kinsey noted that the vast majority of men are only aroused by actual physical contact in coitus. But many others, with a creative imagination, enjoy eroticism through sex dreams, masturbation and voyeurism. Responsive women use explicit erotic fantasies for arousal alone by identifying with the role of the penetrating male.
