I guess I come from a completely different mindset as I'm married but my wife knows that I do this. If I was to judge the private lives of others then I would be a hypocrite. Because I know that eventually thinking in such a way will come back to bite me.
I get the part about wanting it to fill like a relationship when you are with a paid lady but remember they are selling a fantasy. It is not a real bond.
The illusion that you are trying to justify does not sound healthy... For anyone.
