I started punting around the turn of 21st century so have only known internet advertised hookers and agencies.
I have seen a dramatic change over the past decade and it is definitely for the worse. When I first started it was much more of a taboo activity, the girls valued their discretion and punters discretion, there was no apps or indeed Facebook, and most of the girls were British. There were plenty of scamming shit service providers and dodgy parlours but there were also lots of absolute gems. Between 2004-2007 I think was the best time I had. Lots of stunning slim young English girls who gave a great service. Prices then were around the 150 or 160 quid per hour mark so allowing for inflation more than now.
Then what happened is the European invasion happened. An influx of Eastern European scammers flooded the market providing shit services but offering those services at a massively discounted rate. This had the effect of the good quality British girls losing enquiries and bookings and ultimately driving them out of escorting. The British girls that remained in general were either dog ugly, drug dependent, or fat and middle aged who had to offer services at a cheaper rate in any event so didn't feel the pinch by the foreign influx as much,min fact may have benefited as guys looking for British only hookers had no choice but to see them.
Obviously there are still cracking girls around but few and far between compared to a decade ago. Also, hookers now seem incapable of managing a diary or responding to enquiries in a timely manner. This was not the case a decade ago when a response was often instantaneous.
The biggest problem now though is escorting is not a taboo thing to do, for girls it seems a pretty acceptable thing to do, the media is much less judgemental and this has resulted in hookers not worrying about their discretion as much, but also not giving a flying fuck about punters discretion.
Again, not all hookers disregard discretion, but a decade ago hookers were much more discreet in general than now.
Seeking arrangements is claimed to be where the decent young British girls are but in my view guys are naive in the extreme to join a website that requires credit card details to join. It just puts men on the Backfoot as it is all too easy for girls who throw a tantrum if a guy decides not to continue being a sugar daddy to make false accusations against a guy and he is then easily identified. And of course there is the risk that site suffers same fate as Ashley Maddison so I don't see that seeking arrangements is an alternative or new way of punting.
Hopefully, if Brexit wins and we tighten our borders up and make it harder for Eastern Europeans to come to this country and cancel any claims to benefits for these people etc, we might see a stop to the saturation of Eastern Europeans which may encourage back young attractive British girls .
