Generally you would leave your knickers on When I've gone to places like Endota etc, they will ask what parts you'd prefer they work on, and will cover you with a towel and only uncover the bits they are currently working on. Generally most places start with your back, neck, arms, then do legs/feet. They get you to flip over (while holding up a towel for privacy, then massage the front of your legs, arms, hands, shoulders, head etc. They'll avoid the more 'intimate' parts of your body tehehehehe - unless you've booked a massage with a happy ending from a special kinda massage palour

Good idea to wax or shave your legs before
