My boyfriend says he never blushes... Challenge accepted! He's very outgoing and he doesn't get embarrassed. Please help! How do I win the bet?

Most all girls want him. So, girls flirting is everyday with him. I'm very different from those girls and he likes only me. I'm not super flirtatious, but I'm not sure flirting will do the trick. Im not going to say anything dirty to him cuz Im Christian. I haven't known him that long, but you'd think I'd see him blush by now. Which hasn't happened. Please help! How do I make him blush?
