I'm so flattered to be the topic of mild debate.
I'm sorry if I gave the impression that I was blowing big bucks wining and dining girls or taking them sightseeing or traveling to get them into bed. That's absolutely not what I'm doing. I'd estimate I spent roughly ยฃ1200 last year, and ยฃ750 of that was just airfare. Then there's lodging, local transportation, my own food, my own sightseeing, and so on and so forth.
So what's left? Well, on a day where I'm kept up 'til 2 AM because she wants to do it three times, I might have spent ยฃ10 total. There are days where I maybe spend more (I did do dinner-and-a-movie one time, in the middle of a whole week of the three-times-a-night business) but there are also days where I spend nothing at all.
I left probably ยฃ20 on the nightstand of the girl I saw for a week, at the end of the week. She's not a pro, she has a (very respectable) day job and doesn't talk about P4P; I just leave her a little bit, and I make sure I tuck it under something else so she doesn't find it right away. Another girl who I saw a few times during the year, I've never given any money at all.
So if mongering requires the girl to be doing it for money, I'm not a monger. If it just requires the girl to be doing it, and coincidentally getting money, maybe I am, some of the time.
