Frottage, more commonly known as dry humping, is the act of achieving sexual pleasure with a partner or partners, whether naked or clothed, without penetration. This can include using almost every part of the body, including the buttocks, the breasts, abdomen, thighs, feet, hands, legs, and sexual organs. Frottage can include mutual genital rubbing, sometimes called genito-genital or GG rubbing and most of the other forms of non-penetrative sex.
There are many reasons a couple may choose frottage. The most common reasons are as a form of foreplay before intercourse or as a method to achieve sexual gratification without the more sexually explicit (and in some circumstances, forbidden) oral, vaginal or anal sexual intercourse. Often young people will use frottage as an earlier stage of sexual intimacy before more explicit contact is desired, or as a substitute to intercourse to maintain a higher degree of chastity. Also, frottage can be done without getting undressed.
