The OP said reputation is the "main ingredient" in being a hobbyist, I'm saying that's completely false. First, a hobbyist has to have the real "main ingredient" and that is MONEY. You may like seeing a guy because he's nice, good looking, clean, great in bed, or any number of reasons. You may offer him more "services" or OTC then other guys because of these things, but what got him in the door to begin with??? ... MONEY. It's called P4P for a reason. How many free sessions do you give away a week to guys solely because they have a "good reputation"?
Hell ... this is only a tiny fraction of the escort/client population in the world here on TER. Reputation has almost no meaning in P4P really.
I never thought I would say this but ... where is CPA when I need him?
