As a woman I hate to point this out, but this is something I have observed from time to time (and I'm guilty of it myself). Girls don't always want to seek out girl characters. Or girl artists for that matter. I remember reading about a Beatles concert in the '60s that had a well known girl group as the opening act. Apparently a lot of the females in the audience got up, moved around, were clearly not interested when they were on. But as soon as the Beatles came on, they came back and were completely into it.
