Frottage

Frottage is the general term for the act of rubbing any part of the body, including the buttocks, the breasts, abdomen, thighs, feet, hands, legs and sexual organs against the sexual organ of another person; this is done whether naked or clothed and is more commonly known as dry humping or dry sex. When frottage includes genital-genital rubbing, it is sometimes called genito-genital or GG rubbing.

Couples may engage in frottage as a form of foreplay or simply as a method to achieve sexual gratification without the penetrative aspects of vaginal, anal or oral sex, which may also be their personal way of preserving virginity or their way of practicing safer sex. Often, young people will engage in frottage as an earlier stage of sexual intimacy before their idea of more explicit sexual contact is desired.

Other terms associated with frottage are:

Princeton rub, Ivy League rub, and so on are slang terms referring to male-male frot or intercrural sex or both, presumably surviving from the days when these colleges only admitted men. W. H. Auden was proud of having been the first person to use the terms Princeton rub and Princeton first-year in print.

The term frottage derives from the French verb frotter (i.e., to rub). Three terms derive from frotter. These include frottage, the sexual act involving rubbing; frot, the sexual act that refers exclusively to male-male genital rubbing without penetration (but may also be referred to as frottage); and frotteurism, a paraphilia involving obsession with frottage or performing frottage non-consensually (e.g., pressing one's genitals against a stranger on a crowded subway); this was once called "frottage," but the usage is no longer acceptable.
