IS it a BIG DEAL???? Toby, where are you from? How old are you and how many serious relationships have you been involved in? Honey, let me talk to you like a mother......and we really NEED to talk. Are you living in America, NOW?
Let me answer this way, if you don't mind.
Since you are asking if this is a BIG DEAL, I take it, you believe it might be a BIG DEAL if your girlfriend is not a VIRGIN. BTW: VIRGINITY IS NOT "TAKEN".
Toby, good man, if it is important to you to marry a virgin, I must tell you that you will have to start dating ugly, obese 12 year olds. Sorry, but Realistically, that's the best advice you're gonna get. Good Luck?
