I also look to date younger than my age, just because they are more open too all sorts of relationships, and I am also attracted to their freespirit and their lack of jadedness towards men.
Boy that's a big old bag of ASSumption there.
I can honestly say that I'm MUCH more freespirited than I was when I was younger. And actually much more accepting of men in all their varieties and permutations. I also have a lot more confidence, DGAF what others think of me, and make much better conversation. The times I dated much younger men (they sought me out, I wasn't looking) they all complained that women their age were high maintenance, needy and superficial. Now, that's an ASSumption as well, but my point is, you may be looking in the wrong places if you're looking for free spirits.
