Got any advice?

I work at my local Taco Bell and I met this guy that I really like around 4 weeks ago. 2 weeks after we met he kissed me and we became a couple. we're really comfortable around each other and he even dropped the L bomb already. I said it back and I meant it too. I can't tell my parents because they think he's too old (I'm 16 and he's 19) and they absolutely refuse to let me even have guys who are friends. I've never done anything to break their trust when it comes to this sort of thing either. I keep thinking that I'm not really thinking clearly about this and that I'm making the wrong decision. Any advice?
