Married, Having An Affair!
I've been married for many years to a good man. however, I'm also having an affair with a married man. He's older than me and has been married longer, and we both love our spouses and families, and have no plans or desire to end our respective marriages. Yet we can't stay away from each other. The sex is incredible, but we also love just spending time together doing just about anything. We both have guilt pangs about it every now and then, but not enough to keep us apart.
Believe me, we both entered the relationship with our eyes wide open, with full knowledge of the potential consequences. We are NOT naive about it. The joy I feel is incredible, and I feel more alive now than I have in years. It's an exhilerating ride.
