In my late 20's I had a relationship with a woman in her 40's. She made the first move by sending me a flirty note. But I definitely was attracted to her and ready to go on a date. It turned out out we had quite a bit common and were together as a couple for about a year. The sex was great but if we didn't also have a mental and emotional connection it wouldn't have lasted that long.
I thought everything was fine between us. But then one morning, after a minor argument, she broke up with me and refused to explain why. I think age was probably a factor as two people with that many years apart are typically at different stages in life. She was hot though!
