Female massage doctors?
Just walk into any Chinese massage shop. The ladies there are all "massage doctors" and will happily offer extras.
You can tell they are "massage doctors" if they have a chart on the wall of a human body with all the acupunture and reflexology points indicated.
Only a real "massage doctor" would have such a chart.
If they dont have this chart don't trust them as they are not qualified "massage doctors" but maverick "handjob specialists" posing as "massage doctors"
