you make good points.  my mind was in the mode of  school sweethearts.  she's a fresh or soph, he's a senior when they meet...later, he graduates, she's still in high school. the only thing that may have changed for those hypothetical 2,] is  a year older for both.  but yes, I see a bigger picture when you bring in the factor of where it's made a scoring game, or drinking game -  that should be rape....god forbid, even if the young girl consented.  but that is a sexual offense no doubt.  I guess this what a jury or judge decides.
