oral sex?

Elizabeth
So I recently had my boyfriend spend the night at my house and we cuddled for a bit and watched tv and then we went upstairs and he was supposed to have his room and I had mine but I didn't wanna leave so I kept getting him to come in my room and then I'd go in his room. As I was walking back to my room he said if I sucked his dick then I could come back in and I was nervous as hell but I did it. I feel like it's way too soon and I'm way too young. I am turning 16 tomorrow and he had just turned 18 a few days before. 
Is it too early to be doing things like oral sex and things like that? We have been dating for 2 years in May. The thing is that I don't want to get into a relationship with a guy and get my hearts broken bc he only uses me for my body. Did I not wait long enough?
