I dated plenty of older women in my University years. Never really had much in the way of a relationship though, nothing very close at least. I attribute it mainly to the maturity gap, I didn't really grow up until after I was married, when I had my first kid.
I will say this, for me, dating younger women was certainly a lot easier. Dating older women can be... how should I put it... educational. The oldest I went was a 7 year gap, I was 18 and she was 25. Older women who date younger guys, in my experience, are just looking for a fun time, not a real relationship. So I don't think I can relate. My experience was more that younger women were the ones interested in relationships.
