I was 23 when I got my braces, and nearly 3.3 years later, after undergoing surgery as well, I had them removed. I spent part of my braces in an LTR and the last 2 years being single and gaming girls.
Let me tell you one thing: I NEVER had problems attracting girls with my braces, and I used to smile all the time! I've had plenty of chicks in my bed, and some of them even giggled and fessed up how they thought it was kinda hot to make out with a guy wearing braces or how they always wondered how it would be. So I wouldn't worry about that.
As for the pain: It'll go away soon enough. They glued a metal bar to your teeth that really wants to get back in it's original arced shape. And since the brackets on your teeth are bending it, the metal wire is putting pressure on it and pulling your teeth in a certain direction, causing lots of stress on your jaw bones. Your body will need 1 or 2 weeks to adapt to this. Esp. since you're a bit older and your braces are brand new, the pain will be around for some time. Just avoid eating stuff like baguettes or breads for the time your teeth hurt: Chewing is a hell.
Make sure to keep your teeth clean. Use toothpicks to remove food underneath the wire and between your teeth. Use a SOFT HAIRED toothbrush and a toothpaste that's whitening. Without it, your teeth will start to stain and get yellowish. You want to avoid that as much as possible. Good luck with them, I know what kind of hell you're going through.
