He's my first boyfriend - should I tell him?

Anonymous
I've been dating this really great guy for about 2 months now. Things are going extremely well and getting pretty serious..! I'm pretty open with him but honestly he's my first boyfriend ever..! And I'm really scared to tell him that..I don't want him to think I'm some lame prude girl who never had a boyfriend, I mean I've gone out with others guys before and dated before him but now he's someone I'm really serious about.. Should I tell him he's the 1st boyfriend I've had.. Or does It really not matter? Guys seriously what do you think?
