generally i find myself physically attracted to females closer to my age (20) but I am more mentally (as in what actually matters to me) attracted to older women (25+) due to their higher level of maturity (normally) and much more experienced and appropriate understanding of what it actually means to be an adult.
I am not saying all females within an age range of 18-22 are immature, but god damn is it hard to find one who is mature and open to a relationship.
Yeah the ability to keep a clear head in almost all situations and act like an adult and have a maturity level that is at least relative to your age is a definite requirement when I look for a partner. I can't stand 20 year old "adults" throwing hissy fits for childish reasons and having an emotional collapse every time their best friend doesn't invite them to some big shindig.
And yes I realize that a lot of guys are also very immature (even possibly more so than females in the 18-22 age range), however I am straight so its really that i am just not that interested
