TIFU by oversharing with coworkers

I (24F) fucked up by oversharing about my dating life with coworkers. Everyone at this job is around my age and we have about 10 to 20 hours of office time in this role. I have 2 to 3 friends that I trust at work. This summer, I went through a gut wrenching situationship that altered my views on dating and I hadn’t dated since. I recently downloaded Hinge and began going on one date per week and have had some pretty good experiences. I ended up going on a date with a guy who ended up having a micro penis. I was totally shocked by this and wanted to ask if anyone else had had this experience before so I decided to tell a few coworkers that I trusted. They all egged me on, and were laughing as I was telling the story. Two even shared similar experiences if they had had. Obviously, I’m aware that this isn’t safe for work, but I was so shook from the experience I had that I wanted to discuss it. I go into supervision with my manager and at the end she starts saying that she has to talk to me. She starts by asking if I’m OK because she notices I’ve been making some pretty big changes. I said that I feel fine. She said that it’s been reported to her by multiple people that I’m having not safe for work conversations, and I am having a sexual harassment written warning. I am absolutely shook because the people I spoke with are friends and were laughing and egging me on. Even asking for more information and updates. I feel totally humiliated and embarrassed. I can own up to the fact that I shouldn’t have been talking about that at work but sexual harassment feels really extreme. I had to sign papers and apologized profusely. I really don’t wanna show my face again and I’m considering becoming a bartender instead because I’ll likely make double the pay. Someone please help me feel better about this!

TLDR; I overshared about my experience with a micropenis and got written up for sexual harassment.
