Losing their virginity...that's a funny phrase, really. I don't know how many of us have thought about this.

"Help! I lost my virginity!" (searches under bed, behind couch, desk drawers) "Quick, send search parties into the woods, it doesn't like to be alone! I need to find it again!

Under ordinary circumstances, virginity is not "lost." It is discarded, preferably at a time that feels right.
