That's under the assumption she actually wants you touching her. I'm sure all if not most mpa's have received a NR massage from a client they don't click with.
From my experience a Nude Massage there is no touching. Touching begins with a Nude Reverse.
I think I see where MPA2 is going with this actually, when you really think about it, it makes perfect sense. On a NR men are more likely to massage and touch back, whereas a BS there is more of the girl BS'ing than him massaging hence where she is getting the mileage from.
I could be wrong but that's what i'm getting.
