What Crime/legal Classification Would This Fall Under, If Any?

TL;DR a man posed as a potential customer for my business, wasted my time all day, got me to meet with him on zoom, and then exposed himself masturbating to me. I feel violated and I know there is nothing I can do legally because I don’t know his real name, but I’m curious what crime something like this would fall under, if any.

Ok so I had a bizarre experience last night. I run a small tutoring company in addition to my full-time job. While I was at my full-time job yesterday, a Facebook account messaged my tutoring business page about setting up tutoring for his kid. We sent quite a few messages back and forth, and eventually he asked if we could do a virtual meeting so he could “meet who would be working with his kid.” This does happen often, and it’s never been an issue for me before, so I was like “yeah we can definitely do that” and told him it would have to be in the evening when I wasn’t at my other job. He agreed and we set up a meeting for that night. I sent him the zoom link and he joined the meeting at our scheduled time, but then quickly exited. He sent me a message saying “sorry it says I have a bad connection can we try again later?” And I was kind of annoyed but like “sure.” So I get back on about an hour later when he says he’s ready. I am dressed professionally, acting professionally, etc, and fully expect this to be a legitimate business call. Instead, he signs on, turns on his camera, and I see a ceiling, a lamp, and then BAM him pleasuring himself. I sit there shocked for a minute, yell something at him (I don’t even know what I said), and then end the meeting.

Now look. I’m a millennial… I used to get on Omegle and Chatroulette as a teenager. I’m also just a woman in general so I’ve seen/been sent my fair share of unsolicited d*** pics/videos. They’ve never really bothered me this much before. This felt so much more violating. I guess because it was targeted specifically at me and he brought my business into it? And just the precedent he set in my mind that now anyone could pose as a potential customer with bad intentions (possibly even worse/more dangerous ones than he had)? Idk.

The Facebook account is gone now, and it was completely locked down to begin with so I have absolutely no clue who this person is and probably have zero way of ever finding out. It was obviously a fake name. He never showed his face either. But my question is, was this technically a crime? And what would it fall under if so? I know I’ll never be able to actually pursue anything, but I’m just curious. Thanks for reading this far lol
