I joined Fab in my late thirties so used to consider that I first swung at 38.
However, when I was younger, I worked in a pub and was invited to join a threesome with one of the regulars and his wife. Who was I to disappoint?
I didn't think of it as swinging then but, looking back, it clearly was - for all of us.
So, I was around 24 for my first time. What about you?
