I think it depends on what your intention was when you hired the guy. I hired a super hot - pretty well known escort - and was clear I was looking for the boyfriend experience. He was so focused on porn he barely made contact - and I'm - a very fit, reasonably attractive guy LOL. PS - the porn did not help him keep his boner. So - for me - knowing what I like and what I'm looking for - an escort staring at porn instead of engaging with me wouldn't work. The more I hire - the more I realize how important it is to communicate what you want - and what are the deal killers for you. Assume nothing.
