tell me about your first experience at a swingers club or similar

When I was a child of around 7/8, in '75-'76, my neighbor/best friend's parents were having a party, my parents were there too, we snuck into her house to get some chips and dips, I remember seeing a glass bowl with keys in it. We grabbed chips and dip then went back to my house, where the older kids were babysitting the younger kids of the parents who were at the party, Ate our chips then went outside in the middle of the night to play 'midnight hide and seek'. It wasn't until later, years later, I was talking to my older sister, telling her about the chips and the bowl with the keys, she told me it was a 'swingers' party! I have never been into 'swinging' probably for that reason!
