Some of these are one therapist moving between you. Some are two therapists, one each, at the same hour. The difference is the price, and we have written both.
The grid above names the formats. It cannot tell you which of them is yours, and for a couple that decision comes in two halves: what you book, and how many pairs of hands book it.
Take the second half first, because it changes the meaning of everything above it. One therapist working with a couple moves between you, and part of the hour is spent watching rather than being worked on. Two therapists, one each, run the hour in parallel: one start time, one stopping time, and neither of you is the audience. On a card the two arrangements look almost identical. In a room they are not alike at all. It is also the choice on this page that moves the total most, since a therapist each is charged as two sessions and so comes to double what one therapist shared between the two of you costs.
Nuru and soapy are the two that want more than a bed. Both involve warmth, water and somewhere to rinse afterwards, and both go better in a hotel bathroom than in a fourth-floor flat with a shower the size of a phone box. Mention the room when you ask about either and we will tell you honestly whether it suits. Body-to-body is the wider family those two belong to and asks nothing particular of the space. Erotic oil asks only for towels, which is why it tends to be the easiest first booking for two people who have not done this before and are not yet sure which of them is the more nervous.
One card on the grid is a length rather than a technique: the overnight, eight hours kept in one piece for the two of you. Couples ask for it more often than the shape of the grid suggests, and usually for the last night of a trip.
If the choosing stalls, book ninety minutes rather than an hour and leave the detail to be settled in the room. Sixty minutes is short for two people, and the extra half hour is where the deciding would have happened anyway.
How long, how many hands, and how wet. Those are the only decisions on this page that change anything, and between the two of you they take about a minute.
Length comes first, because it is the one couples most often get wrong. An hour is a complete session for one person and a faintly hurried one for two, even with a therapist each, because two people's worth of settling has to fit inside it. Two hours is where most pairs land and where nobody looks at a clock.
Hands second: one therapist between you, or one each. It is the line here that moves the total most, and the rates table inside each therapist's profile sets the arithmetic out plainly.
Wet third, and it is only a question at all if the gel end of the grid is tempting one of you. Those formats want a shower and somewhere to stand afterwards. Everything else wants a towel.
The names on the cards are traditions rather than descriptions, and a couple choosing between them by name alone usually ends up choosing whichever word sounds least alarming out loud. A more useful sort is by what you want the hour to do to you. If you want the familiar thing done unusually well, that is the oil end. If you want the hour to stop resembling massage at all, that is tantra. If you want something the two of you could not have arranged at home, that is the gel end.
And if what you actually want is for both of you to be looked after in the same way at the same time, the answer is not a technique. It is two therapists, and then whichever technique each of you likes.
Several of these decisions have a long read of their own behind them. A first booking for two covers the part nobody asks about out loud, and the guides hold the rest.
