I don't date younger guys...with the exception of one that I haven't decided what will become of us...long story.
At any rate, I've dated too many younger guys in the past and have come to realize that for the most part their good for just dating and nothing more. They don't want to get serious cuz they're still young, and they are more likely to blow you off. Now I know that's not true of every younger guy, but I find that some of the guys my age or older just know what they want in relationships and life and are ready to be serious...
But I'm not ready to get serious again, so bring on the younger guys!
