I can't speak for him on this, but, personally, I would forgive this as a Little White lie if you confessed to me before we had sex. I would tell you that there was no Need to lie About it, but O'd forgive it, understanding that you were nervous. I would be less accepting, though, if we had sex and then I discovered that you were indeed a virgin, because I'd be wondering what else you lied About.
Just come clean. I suspect most guys would forgive the lie if you did, because it's not that big a deal.
