Alright, I don't want to seem conceited, but I consider myself fairly good looking (not close to a 10, but above average). I don't say this because I love myself, I say it because I've gotten the "you're so cute/you're so handsome" complinment from tons of different kinds of people, and I get ioi's after barely introducing myself. But the problem is I simply don't know what the hell I'm supposed to say to girls I'm attracted to. For example: This pretty cute girl from the Middle East approached me while I was watching football (American) and in a sort of flirtacious way asked me to explain it to her. It was kind of obvious she had no interest in the Fighting Irish, but that didn't stop me from boringly explaining the basics, which was followed by a slightly less boring conversation about what we did Friday night, and then silence. She's barely shown interest since.
Any tips on what I could have done to turn that situation into something?
Sorry, I know this is a big question, but I'm just clueless and frustrated.
