I'm a virgin, he's very experienced

Do I tell him? I'm kinda a little embarrassed that I'm still a virgin at almost 21yrs old-- and I mean like total virgin never even kissed anyone. I've just never liked anyone enough to want to be with them, romantically speaking, until I met this guy. He is 30yrs old and is extremely open about his past, total open book all you gotta do is ask, he isn't shy or afraid to say anything. I know he likes me back and we've spent quite a bit of time together, only a matter of time before it goes further, and I do want it to go further.... but I don't know if I should tell him I'm a virgin or not. Is it a turn off that I've waited this long? He's the first guy I've ever liked enough in this way to want to have sex with.
