Thinking about a 90 min or 2 hour session? With me it is not just a Lingam but a full body massage and so the main difference:
after about half an hour of massage to back, back of legs and feet the difference is -
45 minutes of erotic message laying on your back
well over an hour of my hands moving over the front of your body.
