I can imagine a few scenarios where I would pay for this. I mean, I've already done the week in Cancun experience with full body massage while listening to the birds and the waves on the beach. And the sauna followed by ice bath.
It's all about resetting the senses and releasing the tension. Feeling clean afterward sounds good too.
Being bathed by someone who cares about you can be really nice, but that's mainly due to the connection.
Don't see the purpose of paying someone unless u oure too fat to reach your back.
