Being in a relationship for 3 years now

So I'm 16 and Im with my boyfriend for 3 years now and sometimes it looks weird to me cause all of my friends are trying new things and meeting new people, and im just stuck, dont get me wrong i mean i love him but is it normal for a 16 years girl being in a relationship for that long? We are kinda far from eachother and sometimes i question i should hold on or move on
