Give the masseuse a bigger tip ?
Keep going back! First thing, enjoy it, rub around in it. Slip one hand down there and get as much of it on your hand as you can and lick it up, with no conscious note of the masseuse paying attention or not. Then tell that person after they are done. Just tell them it was soo sensual and erotic, your juices just flowed from your body. And like headinazz said, give a bigger tip.
Take pictures and write a book about it. Although you'd have to include vegitation or some other attribute to make it unique.
