I had a similar experience with a guy I saw in LA. I tried both therapeutic and sensual, as the two different prices, and there was no difference between the two. If there's no actual difference, there shouldn't be two different prices.
I'm sure it's just a YMMV thing. The massage was really great. I just felt pressured with the extras.
Oh, and to be clear, it was at the Hollywood location, not the Nathan at the Silverlake location.
