I've been hobbying for 10 years now. Rather than bragging about how many sub par Chinese chicks I've paid to go down on me in a rub and tug, I will simply say that in my years of hobbying I've learned to distinguish a true AMP, at which you can find lovely professional providers where full service is the norm, from your run of the mill rub and tug, where the standard is L1, but for extra (note the word "extra" grasshoppers) $$, L2 is on the menu and on occasion full service. The difference being that the average rub and tug girl 1)isn't as pretty because she's not a professional full service provider, and 2) she's likely not cleaning herself up as much as a professional provider would.
One more thing Mustang.....never underestimate the knowledge of the hobby by me or anyone else by the number of posts or reviews on this board. You want to act like you're a BSD on an Internet forum go ahead.....those that really are have no need to show it.
