Actually, Benjamin, you'd be surprised. I recently attended a performance in a coffee shop given by a young man who was studying classical guitar at University. He played a lot of different kinds of stuff, and he did one solo piece by Heitor Villa-Lobos. Certainly not in the same league as Dave Mathews.
He had plenty of attractive and admiring young women around him. Of course, he wasn't too hard on the eyes, either. Maybe you just haven't captured the right sort of dreamy-eyed look that you need to have when you're playing in order to get their attention.
Dreamy-eyed is good. Whatever you're playing. I promise.
