I know it is its own type of stereotyping to say this, but he probably hasn't. Guys aren't harassed that way. And if they are, the socially acceptable responses are different, they have more options. Plus, they are almost always the bigger, stronger person, which totally changes the dynamic. And so they don't understand (with few exceptions).
Most of them don't understand how creepy and threatening it is no matter how hard they try; they can sympathize, but not empathize.
And it's especially hard to stick up for yourself in a situation where you are trying to preserve the client relationship. That's a sticky one. Regardless, sounds like your boss hasn't been able to convey effectively to him that he needs to knock it off. And that must have been especially unnerving being alone in the office. Time to brainstorm some responses to set some boundaries I think.
Hope the rest of your weekend was uneventful and fun! (((Kat)))
