My husband is six years older than I am. I don't find it makes any difference. He's actually the youngest man I've ever been with. I once dated a man 25 years older than me. Although the relationship didn't work out, for reasons other than the age difference, I have nothing but wonderful memories of him. Of all my ex's (not that many!) he's the only one I have any continuing contact with. He's happily married now to another younger woman!
