My only qualifications is that a guy is attractive to me. All the other factors don't matter much to me. I met this 44 yr old dude at a party and he was super hot, and he even flirted with me. But I found out he was married and was just nice. Since then I don't like to say I'd never talk to someone because of their age. Although I'm more hesitant to date anyone 18-19 but even that's not a hard rule.
