Frot (from the French frotter, to rub) is the contemporary term for the erotic practice between men previously known as "frottage": which involves the mutual manipulation of the genitals, full-body sex, phallus against phallus, done face to face and heart to heart. Frot involves both sexual partners rubbing their erect penises against each other and mutually masturbating with their penises in contact, usually embracing while caressing and kissing face to face, although other positions can be adopted. The term was coined by gay activists who scorned anal sex. This sexual practice bears resemblance to tribadism or "scissoring" in a lesbian sexual relationship.Simultaneously stimulating both partners' penises, especially the frenulum (some frot practitioners call it the "ideal point", because the frenulum is the most sensitive part of the glans). Many gay and bisexual men prefer this practice to anal sex, as according to them, orgasm is achieved by exploring the partner's body, with maximum possible body-to-body contact. Consequently, "Frot" is highly and mutually pleasurable for both simultaneously."Heterosexual" culture defines men within the confines of a narrow and sterile idea of how men should relate to each other, both emotionally and physically.
