We (M45/F45) spent the weekend with a Saturday night with another couple (35m/35F). We hosted- they are from about 100 miles away, and we've met with them three times before. Aside from when my wife brought up the topic of Munsters reruns, the age difference didn't seem like a big deal. Saturday evening had three separate "sessions" of full swap play. Where do people draw the line on age? For us, it's about connection and attraction, which (I think) builds some natural boundaries. Too old, and the attraction tends to drop. Too young, and the connection is difficult. Would love your thoughts. One thing I will tell you about being mid 40's and going three rounds- my whole body was sore on Sunday, and I can still feel it today. This is a price I am more that ready to pay...
