Hello 12th Man...,
Most of what I would say has already been said here but let me add a couple thoughts.
To me that's one of the greatest things you've got going for you, that you've yet to give yourself to a casual, throw-away relationship. Because that's not the way most women want it to be. As the one responder said, it's not something you'd tell everyone you met but if the relationship deepened, it would be appropriate.
Men compete in this area and make you feel left out but they lie a lot too. If there's one thing a guy will lie about it's his sexual history and generally to imply he's gotten a lot more than he has. I'd be surprised if all your friends have really gotten everything they claim.
The only negative might involve why you were still a virgin, for some girls might assume a guy was gay if he didn't have a history. But if you're waiting for the right person and the right relationship, that's the 'right' answer.
You don't see the hurt and problems promiscuity brings when you're seventeen, but taking the 'short cut' comes with a price. It means that when a guy does find that one who can satisfy him for the rest of his life he might not be able to keep her, because of what he's already done.
I was a virgin when I was married at 52. I'd recommend marrying a little earlier, but I'm glad I waited for the virgin part.
