Nope. Age is not an issue between consenting adults IMO. It all comes down to yours and her level of maturity and common interests. Personally there are plenty of same age relationships that fail for the same reasons. People expect that because you're X age and she's X age you should be compatible age-wise but who's to say whatever given age, both have matured at the same rate? There's just no static rule to this. Too many other factors to get hung up on the numbers. Life experience, intelligence, among other things... (when I say intelligence not comparing smart with not so smart as much as just saying that the two need to be compatible on this level too)

Idk if I just rambled or if this makes sense. but that's my story and I'm stickin to it. lol

Hope it helps.
