I'm in my early 30s too, and I have to say, I was getting a little worried that I might be getting a little too old to be single, but then most of my friends who got married at an earlier age, really didn't know what they want and lacked the confidence to progress and find something better before tying the knot. A few of those relationships have already resulted in divorce or some hefty break up. If anything growing a little more allows you to choose someone who is better suited to you, and you simply have more of an idea of what you want.
That being said, there's no need to restrict your game to girls that take your breath away. If anything I would aim to approach more girls that aren't so intimidating to allow you to up your game for when you actually find one you feel like you have to succeed with.
As the others have said, nothing wrong with dating the girls in their early 20s.. for me a 10 year age difference is probably the limit, but that's more tied to finding a girl with something interesting to offer up in a conversation..
