I always enjoyed the Playpit and had great times when i was there. The comments here are right..it was intimate, friendly and very sleazy and i sorely miss it.
The Fort was good too, though i remember the smell there. It was the smell of hardcore sex and always gave me boner!
Backstreet is ok but if you live in South London its a huge trek, so don't tend to go.
I go to SOP at Central Station only because it's fairly close and it opens in the afternoons on Sunday's. I like Piss and the Rubber and Leather guys that used to visit there but that seemed.to have dropped of a lot, which is disappointing.
Who knows after lock down what will happen.
Maybe i should start my own club ?
