You do want kids though, that's a huge plus.
So what exactly is it that you're afraid of?
If it's just the virgin thing, just lie about it.
If it gets heated, tell the girl "look it's been a while since I've been with a chick so bear with me". At that point you don't look like a virgin loser anymore, and you have some leeway that the girl will understand, ahem, performance issues?
That would be my advice.
