I'm going to report a coworker to hr after she wouldn't take no for an answer for a date with me
What reason will you give them when you report her?
She is attractive, but she gropped me at a party. That means that she is not right for me.
It's reasonable to report a coworker if she won't stop giving you sexual advances. You may keep getting harassed if you don't.
Actually, she never gropped me at a party.
If there were advances you should report them but if there were not or you or not sure than that would be extreme.
