To me virgin is not a meaningless term. I'm very proud to be a virgin and it has meaning to me. A lot of people I know respect me for it. Some even wish that they had the will power that I do. And if it is a term that "classifies" then fine. Put me in a group! I would love to join!
In response to the question... I wouldn't think of her any different. I would say that no she is not really a virgin but I can see that she wouldn't count that as having sex. I wouldn't call it sex either. I would call it the highest form of disrespect of a woman's body.
Call me wonder woman. Call me dumb. Call me crazy. Call me nerd. Call me cool. Call me chicken. Call me loser. Call me virgin. Call me anything you want. Just DON'T call me for sex until you call me your WIFE. I WILL WHEN I DO!
