I am in a psychiatric clinic and had a small friendgroup of 3 men. Two of them are great and one of them felt a bit off to me. He is not in the clinic anymore though.

All of us went swimming a few times and he made some comments about my chest over the course of multiple days like 'you should have back pains because of the size', 'you can probably float in the water because of your breasts', it made me feel pretty uncomfortable. He has also asked me multiple times if I brought a skimpy bikini and that I would be great at OnlyFans.

Last time we went swimming was just 2 days ago and I wanted the group of us 4 to move a little bit because i was pretty close to the edge of the pool and then that weird guy joked about it being a 'gang rape' situation. He later on sandwiched me between him and the other guy. Before he left he grabbed me around the waist from behind and pushed his face into my back.

Was this sexual harrassment? Should I report this?
