A Reddit user may have been expecting backlash when he posted a bold claim on the r/askgaybros forum: “Frotting is super hot and an insanely underrated form of sex.”Instead, he only got endorsements.“FROTTING IS BETTER THAN INTERCOURSE, CHANGE MY MIND,” another user wrote in a comment.As defined in a 2006 Out article — fittingly titled “What’s Rub Got to Do With It?” — frottage, derived from frotter, the French word for “to rub,” is “an erotic act of rubbing the penis against another surface—sometimes, though not always, another penis.”The term frot, meanwhile, has come to refer exclusively to penis-on-penis action. “Frot is most often done in a front-to-front embrace, where guys can kiss while rubbing c*cks,” Man2Man alliance founder Bill.
