Once you have paid your £15 for the week that is it. After that it is an establishment with consenting adults!
In my recent experience of their new location, on a busy afternoon there might be 15-20 guys there; women zero.
Evenings get a bit busier and because it is quite small downstairs it can feel quite claustrophobic. Whereas in their previous larger premises I could happily while away several hours watching porn and observing other goings on (!), here I find an hour or so is enough.
You have to accept that it is mainly a place for old guys to jerk off, some gays to cruise, some cross dressers etc and the occasional woman to turn up with their partner for some action. But I reckon you could easily go there 100 times and see nothing that attracts you.
It's an interesting place in its way, among the last of its kind in London and I doubt that it will last too much longer. They got forced out of their City Road, London location by the relentless forces of gentrification and though their current location is a bit dodgy, the PC brigade will get them I believe.
