Another thing you might want to consider is why young age play is such a turn-on for you. What is it about it that makes you so hot? Perhaps there is another type of fantasy you could use to get the same result.
For example, I had a friend once who engaged in age-play, and when I asked her why it turned her on she explained to me that she liked her dom "showing" her everything about her body and "teaching" her about sex, all as if this was her first sexual experience, ever.
She also had fantasies where she was a sheltered farm girl who was absolutely naive about all sexual things and achieved similar results that way.
I don't know if that is the part of it that is a turn-on for you, but perhaps if you were able to figure out what it is about it that turns you on, you could find another type of fantasy to satisfy those needs, or maybe several other fantasies to satisfy different parts of it.
Of course, you should be expressing all of this to your dom.
