I think this forum is broadly representative of the way things are these days with regard to punting.
So much has vanished. The Soho walk-ups have dwindled from more than 30 "doors" to a tiny handful. But there is a very, very long running thread on the subject, with members doing there best to keep track of what SPs are working, where and when.
Street walkers have almost vanished from the UK. I remember the bad old days of kings Cross. In fact in the early 80s I was very briefly homeless and for a couple of weeks i lived in a hotel on Argyle Square, whcich was an education.
But now the street walking scene in London is not much more than a crack-head or two, a TS, and a moody Rom, hanging around Sussex Gardens. But even so there is a thread dedicated to London street walkers.
There is also a large section given over to covering massage shops across the UK.
In London and the South East, brothels have nearly all gone. I've lived all over London, and was never more than a twenty minute walk from a brothel. I now live in East Sussex, and the last two brothels in my local town have now closed. I've never had a handle on the "Parlour Scene" in the Midlands or the North, but what I gather from this forum, things are not what they used to be. But the regional threads provide plenty of info, and are a strength of this forum.
