When you massage the back you can either remove the towel or just pull the sheet down just below the waist.
To work on the legs, fold back enough of the relevant towel or sheet to uncover one leg; the same goes with the other leg and both arms as well.
When it comes to your partner turning over, if you were using a towel, tower complete body towel between you and your partner creating a screen to protect your privacy as they turn.
You could also place your legs against one side of the sheet you can grab the middle of the sheet and inform it as a tepee over their body. When you do this, have the client flip towards you. It will make it almost impossible for the sheet to become loose and for the client to become exposed.
Now we know we don’t need all of that. Even though a body’s a body, some clients can be very uncomfortable with themselves and become even more stressed.
