Recently i've discovered that my age is a surprising hurdle when approaching/gaming girls.

I'll be in the middle of a conversation, somehow it'll come up that I'm a couple of years younger than the girl i'm talking to and it tends to come with a really negative reaction, and all kino from then on is met with resistance and it tends to be a bust.

My questions - does anyone else experience this? If so, what do you do to either a) avoid it from happening without lying about your age or b) respond to it when it comes up?
