promise ring

Reagan

So we have been great friends for a long time, so when we got together it was no shock to any of our friends. the problem is I am two years older than him. but when he got down on one knee with a vintage ring like I always told him I wanted, I was shocked. I believe that we can make this work with some real effort and understanding. I am of marrying age, but he isn't just yet. (I'm 18 and he's 16) I just want to know who has some tips for making a relationship like this work. We have been each other's first sexual partner, I was his first kiss, and he's never known anything but me and me him. Please no hate, but any advice??
