If you don’t mind a trip over the Dartford bridge there are a few clubs in Kent, I’ve been to DV8 they let single guys in on Saturday and is really friendly, my personal favourite is Pleasures, always have a good time there, lots of playrooms and a huge bed in the main area if you like to be watched.
Le Budoir in the City is meant to be good but you have to be a member.
Let me know how you get on
