Had our first swinging experience a few weekends ago and, while the place we went to wasn't bad as such, we didnt feel particularly at ease as most/all the people there all seemed to be quite a bit older than us (we are late 20's/early 30's) - are there any good clubs people can recommend in the Midlands (Birmingham, Leicester, Nottingham, Derby, Sheffield areas) where there is more of a younger crowd (though preferably not all single men!) where we might feel we fit in better and feel more at ease?
