Reverse the sexes and tell me what you think. There is a word for the practice: “frottage”. If I were at a dance and a man ground against my leg until he got off, or tried to, I wouldn’t consider it rape, but I would consider it rude and disgusting and do everything I could to stop it including making one hell of a scene. If a man got me alone somewhere, restrained me by threat and/or violence and rubbed himself against me until he reached orgasm or something close to it, I think I would consider it rape and I’d do all I could to have him convicted of assault at the slightest. The same applies to women raping men.
