I had a great relationship with a 48 year old man for a couple of years when I was 18. He was fascinating and taught me so much about life, art, history, politics. I eventually married a man 9 years older, and it worked out fine, although he died after 25 years. I think it doesn't matter too much if a man marries an older woman, unless he wants to have children. Then, the biological clock kicks in. Just make sure they smell good to you if you want a relationship to last. That seems to be a big part of compatibility.
