Oil, gel, foam, skin. An hour reads you; eight hours does something else. We publish techniques and durations.
The grid above names them. What it cannot say is that several of these differ by a single material, and that the material decides the rest.
Oil sinks in. Skin takes it, warms it, and after twenty minutes there is drag again — which is why an erotic oil session keeps returning to the hands to renew itself. Nuru gel does not sink in. It stays between two bodies for the length of the hour, so contact once made is never re-established. That is the whole distinction. Everything else said about nuru follows from a gel that refuses to absorb.
Soapy begins standing, in the bathroom, and is a wash before it is a massage: foam thins, rinses, is made again. Nuru holds one state from beginning to end. Choose soapy if you want the room used. Choose nuru if you want the hour uninterrupted.
Body to body is forearm, torso and weight in place of hands. Naked is what is worn. The two overlap constantly and are listed apart only because people arrive asking for them by different names. Four-hand is not the same massage doubled — it is the point at which you stop being able to follow where the next contact comes from.
Ninety minutes, body to body, oiled. An hour holds one form and little around it. At ninety the pace stops behaving like a schedule. Past three hours the question is no longer which technique but what kind of evening, and that is where the dinner, social and overnight formats sit: the same list, a longer unit.
