I dated a girl who knew how into comics I was/am. She didn't say anything about it. I even got her turned on to Smallville (for a time). If a girl can't handle a guy that still watches cartoons (He-Man, JL, etc.), collects comics, or loves video games then that's her problem. Like everyone else has said, it's not the only thing you do (right?). I still spent tons of time with my girlfriend and had enough to talk about with her. Her and I are both studying to be teachers, so we had that in common.
