Tribadism (pronounced /ˈtrɪbədɪzəm/ trib-ə-diz-əm) or tribbing, commonly known by its scissoring aspect, is a form of non-penetrative sex in which a woman rubs her vulva against her partner's body for sexual stimulation. This may involve female-to-female genital contact or a female rubbing her vulva against her partner's thigh, stomach, buttocks, palm, arm, or other body part (excluding the mouth), and does not always reflect a scissoring motion; a missionary position, as well as other sex positions, may also be acted upon. The term can also refer to a masturbation technique in which a woman rubs her vulva against an inanimate object such as a bolster to achieve orgasm. The term is most often used in the context of lesbian sex.
