It's about a girl who's experiencing something she's never felt before, like when she had sex for the first time. Something eventful in her life that's as big or bigger than when she lost her virginity. So in this case probably love, happiness, and a feeling of being complete. Stuff that she's never felt with anyone else before.
Either that or she's an anal virgin and just lost that for the first time.
