I'm going to assume this wasn't a typo and answer the question as I read it. NO NO NO, your vagina - - tight as it may be - will not hurt your sexually experienced boyfriend. That's sort of like me worrying a mugger might hurt his hand knocking me out. No, that's a dumb simile. Your boyfriend is not a mugger. And the impact of punching a face can hurt a fist.
The impact of your vagina hurting his wang is sort of impossible. Your vagina, is still a warm, well cushioned cavity (for lack of an even less sexy term). I mean, yes, it might feel cramped in there, a touch snug, but worry not, dear virgin.
More likely, your first intercourse will have some accompanying discomfort - to you. Hopefully only a little discomfort/hurt. As such, it's important that you take this upcoming sex slowly and serve as head conductor when you two embark. If he's as experienced as he says, then good, he should be aware of your newness to this and work with you to make the experience enjoyable, rewarding, and dare I say sexy.
Good luck and sleep... tight.
How cute, lol.
I lost mine a little over a year ago so the experience is still fresh in my mind. I remember him slipping out because I was tight was a tiny bit of an issue. Nothing serious though, we still got the job done ;)
