I do believe the influx of EE girls has reduced prices, and services like OWO seem to have become the rule rather than the exception. It don't think punting costs me any more now than it did 20 years ago, even though I can almost always expect extra services like OWO to be included.
It's entirely up to a service provider what she charges. And if I was doing the same work as 20 years ago I believe I'd be earning about 50% more now than I did then. Personally I probably wouldn't pay an English SP a premium over what an EE provider charges for the same service, but it doesn't surprise me that some punters are happy to do so, and for the reasons I've given, it doesn't seem unreasonable to me.
It certainly did when EE WGs first starting coming here enmasse in the 90s AND services like kissing and OWO were often on offer unlike with Brit WGs of the time where kissing was hardly ever on offer as that was for their partners only.
My punting costs have gone down on average from 10 years ago and there aren't many things I can think of that have also gone down in that time that I pay for, newbie punters wont know this though and rightly of course are concerned with what their punting costs them now. The great thing about punting, in London at least is there are WGs in many price bands from quickies and Soho Walk-Ups to hundreds or more an hour, so choose what suits you and punt accordingly. It would be great if what UKP could do is have enough clout to reduce prices but sadly it doesn't in reality, in fact often though not always well reviewed WGs put their prices up as I have seen happening for years which is why a punter has to make a decision, does he review good WGs on here, only by PM and with punters he knows or kept them to himself. What UKP CAN and has done is out many bad WGs and rate many good WGs to help punters decide who to punt with.
I pay what I am prepared to pay and its based up to my absolute max of £200 an hour on the WG, if I rate them irrespective of nationality I may and have paid more to punt with Brit WGs than EE WGs in recent times, if the punt was good its usually been VFM as I see it, what others do is obviously up to them.
