Losing my virginity & dick size?

Hello everyone :)
Soon I believe that I'll be losing my virginity. We've talked and planned about this and I feel ready. But I have a question. I'm extremely tight. Sometimes inserting tampons hurt. I've been fingered (1 finger) and it didn't hurt but he couldn't fit two fingers without it hurting. His dick is about the 6 inches and medium girth. Will my vagina stretch far enough to let him in and am I abnormally tight?
