Tribadism or tribbing is a form of
mutual masturbation, sometimes called
frottage, in which a woman rubs her
vulva against her partner's body for sexual stimulation. The term is most often used in the context of
lesbian sex, but is not exclusive to such. Tribadism sometimes involves female-to-female genital contact, but more often refers to a female rubbing her vulva against her partner's thigh, arm or stomach. Tribadism can also refer to a
masturbation technique in which a woman rubs her vulva against an inanimate object such as a
bolster in an effort to achieve
orgasm.
