possible trigger warning l‼️‼️‼️‼️

so I have a job that I started when I was 33 weeks pregnant. (my daughter is now 2 months.) there is a male coworker who apparently had admitted he had a fetish for pregnant women... weird... I know. it gets worse. He would always touch me and grab me at work. I never said anything bediase he’s higher up at work and I was brand new. I went on maternity leave and came back thinking it would stop. nope. he is still touching me, grabbing me, making sexual comments to me at work. he is 43. I just turned 20. it really makes me uncomfortable and disgusts me. I just know if I say something, I’m worried about my job and the way it will be around him if something is said to him, becuase he will know it was reported by me... what would you do in this situation?
