How to be flirty since I'm deaf?

The best answer I can give you is to be yourself. You don't have to have a perfect image for a boy to like you. If a boy likes you for who you are, it's obvious that he's the one for you. When girls get prettier for him it seems that she is not showing who she really is. By your description, it seems like any boy will like you for your beauty, I wouldn't be worried if your deaf. Consider it a special gift. I hope I helped. You're special and hope you get that kiss
