RELATIONSHIP ADVICE PLEASE?

I'm a virgin. It's not that I don't want to do dirty stuff I just have never wanted to with the people I have been with before. My boyfriend had literally done everything, and I mean everything, with his ex girlfriend. I don't really know how to feel about that. We're very vocal about sexual things to each other and I find myself telling him things I have never told anyone else before. But since he's done all this stuff with other girls I kinda feel like I might have to do these things also. What do you think of this situation and do you have any advice to make me feel better?
