I think the best punting years for me were 1998 - 2010. I now have a London centric list of providers (all UKP multiple positives).
I've noticed over the last year or so, when I search AW (or RP) using my favourite search terms - Cim / Snowball / Swallow there are fewer new providers and many put at discretion that usually means "No!"
Like most people I want a bit of fresh meat occasionally rather than visit regulars such as Crystal, Ruby, Martina, Linda, Angel,Kim, RedRose, Surreysarah etc.
Maybe's it an age thing. I'm having more massages and hoping to get more.
Happy 2019.
