is more desciptive of the "feeling" she creates.
Attitude thus could be: great, poor, real pleaser, energetic, truly present, aloof, etc. As in, "she was ---".
To me, these are more "good or bad" in nature. Does she bring a good or bad energy to the table? This is about HER.
Atmosphere could be: sensuous, relaxed, fun, GND, scripted, etc. As in, "the session had a --- feeling to it". Guys might not all be looking for the same thing, so the "good or bad" of the atmosphere is a bit more subjective to me as compared to attitude. What aura or feeling did her actions foster or create for the session?
Example: She had a great, truely present attitude, which created an intense, sensuous atmosphere.
Or, she had an aloof attitude, which made everything feel scripted.
I realize some of the terms could be used to describe attitude or atmosphere. But in general, she possesses an attitude, and she creates an atmosphere.
