Over the years I've dated a couple of prossies. Neither of them wanted money after the initial encounter and were downright bloody insistent about it.
The fact that the punter even thinks in terms of damaged goods enough to name the thread is evidence that he views her 100% as a prostitute. The fact that she keeps taking cash from him is evidence that she views him 100% as a client.
Any prossie worth her salt would probably have told him to fuck off or fuck off nicely by now.
If it wasn't an experienced poster/punter/reviewer, most of the forum would have told the OP to fuck off by now. And he still doesn't have the balls to post the link.
So he is really asking, "Should I carry on being a stoopid cnut?" Errrr no, you dufus! Look at yourself, and her, through the eyes of everybody else and stop it. Do what you would tell someone else to do in the same circumstances!
Even trying putting the nicest interpretation on it: a prossie he enjoys so much as a regular that he prefers his evenings with her to the exclusion of all else, is a non-starter given his shame at providing an honest link.
Love is the mutual attraction between two people. Punting is just slightly better than falling in love with your hand when you wank a bit too often.
