When I got my first m4m massage, price was 50, i tipped 50, which had a very quick but full full service. repeated once there but i requested just massage, tipped 50.
After reading some discussion in the forum, i realized that might be good if therapeutic, but not good if its extra extra. But i asked the massuer via message, he said it's ok, i don't know if it's real ok.
This week i had my third massage, price was 70, i tipped 100, for the hand. I thought it should be fine.
But now reading this thread, 100 might still sit in the range, but i am afraid if it didn't show my appreciation to him since it's really good. next time i will tip exactly 100%.
But it total 200 for an hour, i think i will continue, but reduce the frequency a bit.
