Ignore the heat, you're doing fine. ;) Our culture is biased in favor of same-age relationships, and has been since the fifties (I blame mass media, particularly the movies.) I think that's at least part of the reason for the divorce rate. I can say for sure that I benefit enormously from my husband's 13 year age advantage on me-- he's always been calmer, kinder and more loving and more forgiving than any young man I ever knew. In fact, I've learned a lot from him about how to be.
Like Bogart/Bacall films? ;)
I'm with you. I like the freshness and vitality of a younger woman - though still keeping it relatively reasonable. I find large spreads in ages to be mildly creepy, and they get creepier as the spread widens. 5, 10, 15 year spreads is fine and based on what I have witnessed, works just fine.
I'll keep it up. ;-)
