I have been with my wife for over 17 years, married for 5. We're in our 40's and have always had a very adventurous sex life mostly due to me. My wife was very inexperienced when we got together, even though she is 4 years older than me, so I corrupted her you could say. We have had many threesomes a few foursomes and I have had several woman lovers during our relationship. But for the last 7 years we have been greatly monogamous with a few diversions. I have encouraged my wife to take a lover and she finally has. She started seeing a friend of ours and it is so hot. He is an ex-marine bodybuilder and he really turns her on. They have only had sex a few times but it is becoming more regular. I am not threatened in any way. My wife and I are truly in love with each other and we discuss everything including teaching her to Sext. Her boyfriend and I even plan what he is going to do to her and where. I have always wanted to have this openness with a partner and it was worth the wait. I have a nonstop sex drive that I am told is amazing for my age. I can have sex 2 to 3 times in a row. I can last for hours and I want it like that every day so I have been playing with the idea of finding a girlfriend of my own but I am very content right now with my wife's escapades. I am very interested in hearing from men, women and couples about their experiences in this area.
