Should I tell him that I'm a virgin or not?

[:)]

Hi so I've been talking to this guy over twitter for a couple days (we live in the same town and have mutual friends just haven't spoken/met before) and I really like him so far, I'm not sure if he likes me as he's really popular and loads of girls want him but he has said he'd come meet me soon. Anyway we were talking and the conversation got a little you know because he asked what I was up to and I said I just got out the shower and was cold. I really don't want the conversations to get sexual so soon cause I'm afraid if I tell him I'm a virgin he might just see me as a challenge and have no relationship interest in me. How do I avoid this? I can't lie to him but I don't want to just be seen as a challenge and any thought of a relationship go out the window. Should I be up front and tell him I'm a virgin if the conversation comes up? We're both 17 btw and he's not a virgin.
