After a few months of dating my girl, I got her into comics. She doesn't read alot of Marvel, but she's hooked on New Avengers. Her favorite titles are Supergirl and All Star Batman and Robin, and Green Lantern Corps. But her obession lies with Buffy Season 8.
Not to sound full of myself, but not all comic fangirls are ugly. Actually my girl is really pretty, and anytime I've seen girls at the comic store, they've all been better than average. They didn't look like your average comic reader, but once you start talking to them, you realize they are fangirls.
