You're worrying over something that is frankly irrelevant.
But also, you have the wrong impression on pretty much all of that.
Believe me, there are plenty of fans of such things who are much older than you.
Instead of worrying about what others might think though, which is typically pointless, just go with what you like. To do otherwise is a road to madness.
Besides, what most people think of as "childish" and "mature" is usually bloody stupid, if you think about it. The same people who might say that your interests are "childish" will promptly go to some dumb bar, get themselves braindead drunk, make a total drooling idiot of themselves, and so on. Yet if confronted about it they'd declare themselves to be a totally mature adult. Ridiculous.
Real maturity isnt blindly following the whims of others or letting their opinions control you. Real maturity is simply being yourself, in the face of that nonsense. Being who YOU are, instead of who a bunch of idiots think you should be.
