Grinding is the act of two individuals rubbing hips together in a rhythmic motion. It is similar to dry humping but is often less sexual. It is frequently done on dance floors or other public or semi-public places. Typically, the term refers to contact with erotic intention while both participants are fully clothed.
Grinding can also refer to masturbation performed in a similar way. In this case the participant is clothed and grinding against an object like a pillow, sex shape, or couch. As the popularity of grinding rises, multiple manufacturers have crafted grinding-focused toys like the Orion VibePad 2, Liberator On a Mission, Rocks-Off Ruby Glow, and the Wild Flower Enby 2.
Although direct, unobstructed contact of the genitals never occurs, it is entirely possible to orgasm through grinding, and some people may prefer it due to the diffused sensations.
