For us the guidelines are over 30 and under 55. We are 43 and 44 today. We have made exceptions to those guidelines before and we will again. It all depends on the specific couple. The thing we have to consider is that my parents were swingers and my daughter and her husband are swingers. We really do not want to run into a couple who has been with either of them so we try and stay out of the age groups we think they like.
All you people with young kids..wait till they grow up and become just like mom and dad.
