i dont understand, i really dont, the first person who felt vibration, likely under their bottom in a car on a gravel road, and said: i would love to feel that between my legs can people even just pause there rest there on how unnatural and off that is? to desire that? what body part has ever vibrated? what fingers? tongue? penis? anything? why would anyone want an impersonal inanimate machine there? in such a private personal place?
