a bloke meets a girl in a club one night and they start dancing/chatting etc. at closing he takes her home, and after some heavy petting they end up in bed and proceed to shag each other senseless all night. In the morning the man turns round and says "blimey luv, you really know how to satisfy a mans desires" she smiles sweetly and replies coyly "I ought to sweetheart...........i used to be one"
