I see your point. Perhaps there should be a separate charge for non-penetrative sexual assault. Because, IMO, emotional and verbal assault that are sexual in nature ARE forms of sexual assault.
I have been trapped by a man, thinking he was "cute", asking for a hug and kiss while blocking a doorway and I was in a state of sheer panic, alone, and trying to get past him.
Also, I was in an elevator with a work superior who told me dirty jokes that made me want to puke, and once the elevator opened, said is a loud voice "oh, WOW! Thanks, that was amazing!" to an audience of office workers and clients. I wanted to DIE. He was fired, but not for four more years and because of numerous complaints of the same kind.
I was not one of them; I did not want to be seen as a troublemaker. And I wanted to keep my job.
But since I was not penetrated and had no semen or hemmoraging to show, there was no assault. I guess.
