Lol, I'd take this comment with a pinch of salt. Not been but from reading it's a few couples and lots of single guys standing around hopefully and mainly wanking over the action.
obviously you haven't been to the phoenix club london ( formally LMP), The private club aston birmingham, r3tro club walsall;
in fact a whole host of such sex clubs or events around the UK ;
not talking about those waste of space swinger events where everyone is trying to impress some grossly obese or hag of a bored housewife
but sex clubs some are marketed as "swinger clubs" but you are 'guaranteed' sex by paid talent attending,
also some swinging couples, single females do occasionally attend these particular clubs/events as well.
do some fucking research on here and google , in fact why not attend such a club/event and see for yourself, so wind your neck in
