Can someone explain 'age play' to me please?

My partner and I have been role playing since we met 5 years ago and I've seen no change in him. I think it's really a case by case situation and that's how I deal with it...if a guy starts asking me about my own family or for a scenario that I don't feel comfortable with or otherwise creeps me out, I don't do it. The things that I fantasise about would be illegal and I wouldn't want them to happen to me or anyone else in real life...they are purely fantasies.
