  1. If I’m not mistaken, doesn’t tribadism refer to rubbing a vulva against a partner’s body part, but not exclusively another vulva? For example, vulva to thigh rubbing.

    • Indeed you are correct! The definition of Tribadism is as follows, “Tribadism is a form of non-penetrative sex in which a woman rubs her vulva against her partner’s body for sexual stimulation, especially for ample stimulation of the clitoris. This may involve female-to-female genital contact or a female rubbing her vulva against her partner’s thigh, stomach, buttocks, arm, or other body part (excluding the mouth)”

      Thank you for catching that!
