Im tantrick trained, when I spray the inner arm, the client is standing facing me with the insides of both arms showing and palms pointing to the floor. My question is, how far do you usually go down the inner arm to avoid tan on the palms? I don't think I'm going down quite far enough - I tend to go down to about half an inch from where the palm starts and find that it sometimes graduates to nothing but before it should but i'm nervous of going just that bit too far.
