I know wot you mean.... but believe me... they are not all sat waiting in clubs either.
There is more single bi fems than you may think you know... you just have to seek them.
We were going to visit the Office club in Bristol on a couples night. Before we arranged to go we got a PM from another memeber who had been to the office telling us that they went on a couples night and single men are allowed in, figure that. Dont know if thats the same at any other clubs but it sure put us off going. We dont mind single men being there so much but were also told by several users that the single men at the office hang round the pool table being loud and only approach the woman from a couple when say the man goes for a WC. Very slimey in my opinion. I think you need 5 very good referances for a club before deciding to go as a first time swingers event.
