I was talking with another swinging couple one day and a topic came up of what was your lowest and highest age limit in swinging.
I found that most couples wont swing with anyone their kids age or younger because it would be like having sex with your daughter/son. Which got me thinking about the psychology of swinging.
Now my daughter is 24 and I have been with many women her age and yonger, two being one of my best friends daughter and another a good friend of my daughter. It seems if people start to relate swinging other the rest of their lives it can put walls in your swinging lifestyle, if you are always thinking about your kids then you will never get over that wall, the best thing is to not over think and keep your swinger lifestyle away from your regular life.
Thats my two cents anyways.
