Reporting a coworker advice

Hello ladies!

Recently I was doing a night shift orientation with a male. At the beginning of the shift we were talking about our separate relationships and all seemed normal. However, things got a bit odd when he kept asking me if I was wet, telling me he was hard/needed to jackoff, pointing out the various places in the workplace where only he had the key so sex would be easy. I felt uncomfortable but at the beginning I talked/joke with him about smaller comments until I mentioned that this kind of talk was inappropriate for the workplace. Things had slightly calmed down towards the end of the shift until it was almost 10min until the end when he came up behind me and pulled my hips towards his so I felt his erection.

I recently reported him to my employer and went through a very uncomfortable interview with them. They said next steps would be to interview him and then re interview me.

This is really stressing me out. I’m worried he will flip it all on me since I played along with it earlier on in the night. I’m worried this will be a lot of stress and I will get into trouble and I won’t be believed. And also working with him later on will be an awful experience.

I’m honestly trying to decide if I should quit since I’m feeling like this will end negatively and go nowhere. I also feel like this is a really bad first impression on my new employer.

What do I do?
