Okay sorry, I at one point must've used the word sexual harassment interchangeably with sexual harassment. Sexual harassment usually is used in lawsuits, because it's nebulous.
I meant sexual assault. Assault of any sort is defined as the above, to give the person reasonable fear that the action will take place. Crest is being sexually assaulted.
Does this mean that Moby should be immediately locked up? Well... no. Part of this is determining the person's reaction. Crest didn't want that sort of rapey behavior, but if she kinda tones it down, there's a chance Crest can shrug it off. Assault exists only as long as the fear of the event persists. If she lets it go, it's like he was assaulted but not anymore. As in, if Crest grows to like her, he doesn't need to press charges.
The fact that it is a date doesn't matter (this is why date rape is still rape). In this matter, even being married doesn't matter too much. Typically, most dates don't go this way this soon, and if we look at the "date" in question, it was starting to go south at the point where she started removing her shirt. As in, the implication behind exhibitionism is that you go up to them either just because you like showing off your stuff to random strangers or because you want something. I've looked back at the comic, she talked about how Crest is attractive and while he was still going "Huh?" she starts ripping off clothing. Mood is wrong here. If they had a nice time, and were kissing or stuff, this would be the right time to start removing clothing. Right here, we are all still going "Huh?" because there is no logical jump from casual dating with lukewarm reception to stripping off clothing. If they came to the date nude, if they were already kissing, if Crest asked her to do this, if she asked to do this, even if Crest said he was having a nice time and seemed to want it, the mood would be better than this. This came as a complete non sequitur to audience and Crest alike. He didn't ask for it, didn't want it, didn't even understand why she did it. At this stage of the game, she could have done this, if they were having fun, and both of them were involved such as "hey this restaurant has naked fun time, wanna do this?" The same thing as him suddenly removing her shirt. With no context (even checking for ticks) it comes across as weird and sorta creepy.
The above definition was for physical assault. The definition for sexual assault is just to replace the latter part. If you have reasonable suspicion that you are being molested, this is enough.
