Jason1, I am no one to give romantic advice, but I must give a thumbs up to your tastes. All things being equal, younger chicks absolutely rule. As a friend of mine would say, suppose you end up spending the rest of your life with a chick you're dating. Hey, that may be looking forward and indeed it is, but at some point it happens to the vast majority of us. Let's say down the road you're 35. Would you rather wake-up next to a 30 year-old, or a 40 year-old? That's the difference 5 years can make.
Of course, the problem is that younger chicks are not always mature enough. They may be fine for a hit and run, if that's your thing, but not for a relationship. I'm at the age where I will look for marriage qualities in a woman. This doesn't mean I'm looking to rush into marriage, as I think people should date at least 2-3 years before saying "I do", but it means I'm old enough that if a girl radiates immaturity than I won't give her a moment of thought, because it obviously wouldn't go anywhere.
