Tribadism
More commonly known as scissoring, is 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, arm, or another body part!
It may also involve the use of a dildo or double penetration dildo. It can sometimes refer to a masturbation technique in which a woman rubs her vulva against an object to achieve orgasm.
