In my book that's way to young Me i date only girls same age or + (i'm olso 24) But why ascks as this is a webmaster forum ...
Depends where you are at. If you are in some country where the police can be bribed and all, there is not much of any risk in it. Other wise stay on the safe side. I am not telling you to take advantage of her. Proceed further only if both of you like each other.
