That's quite a leap to come to from what I said but in answer to your question, their entitlement is as valid as anyone else. I imagine some lie to their partner, some don't have a partner and some have a partner who is perfectly ok with her lifestyle. I bet though there is very few who have a partner who regularly punts, reviews WGs on forums and asks questions about wether he should try and date the girl he often pays to fuck,
In these terms the punter/WG 'relationship' is actually well balanced, it's a relationship of equals. Just as you might say 'what woman would want to go out with a guy that sees women for sex', equally you could say 'what guy would want to go out with a woman who's a sex worker' (apparently this girl doesn't sell actual sex, only HR. For the purposes of this thread we'll take that at face value).
In both cases, for various reasons both the man and the woman is likely to return to their previous activity. We all know this well.
In this case the guy is 25, we'll assume the girl is similar. In a way they are possibly not the 'hardened souls' like perhaps the majority of UKP membership, nor like many scheming WGs. If she's only doing HR she's perhaps stumbled into this to make ends meet for the time being. ie perhaps she didn't come into the UK to sell sex, also she's probably independent. The guy in this case doesn't seem to be a Jack the Lad. Seems genuine. Perhaps a little naive (but we probably all were once).
My take on it? Compared with if he met her in a bar, it's probably got 20 times more chance of not working out, and if it doesn't, 20 times more likely to end badly. 20 x 20 = 400...so 400 times more likely to end in a shit sandwich.
But if it does work out, even when she's got a headache she could probably wank him to Heaven with her
experienced hands and a bottle of Johnsons, and he'd be just as happy and then roll over to sleep straight off.
I'm inclined to say to the OP give it a whirl, let it run its course, but all the time watch out for the warning signs well documented here by the experienced heads of UKP.
Now I'm not one to say c'mon, post up her link so we can all have a look. However, in the interests of his own safety, 25yoguy must post up all the details here (purely so we can all make sure he doesn't get led astray of course

).
