I am involved with a woman 9 years older than I, and she is every bit young at heart and looks closer to my age. We are compatible and happy with our life, I wouldn't consider trying to seek another woman only to have a closer age range. Why should I? People have done it the "acceptable" way for years, and yet these relationships end up in a 50% chance for divorce. So if it works and both involved are happy, then pursue the relationship for yourselves, not what others think should be "righteous".
