I don’t think the three of you would like a club to be honest, unless you wish to pretend you are at a dinner-dance at the church hall with your grandparents. No in fact that is unfair, the church events would be less formal 
We have visited over a dozen clubs or Naturist campsites and for us they are great for wholesome naked time, but even holding hands or a peck on the cheek is frowned upon.
Members at clubs seem to want you to join in, play boules or eat a communal meal etc which can be a bit overbearing, whereas a campsite lets you do your own thing more.
The age profile of UK clubs is mainly 65 upwards, usually wandering round in bathrobes as if convalescing from an operation.
You and Pen should stick to the back garden like we do and wave at the neighbours while they suffer their frustrated vanilla lives
