I was sexually assaulted at Disneyland

This happened about 6 years ago and i’ve never told anyone. My boyfriend used to frequently buy us Disneyland tickets. He had the money for it so I never objected, and it usually was a great time. At this point in our relationship things had started to get kinda weird. He started to get weird. We were at Disneyland one summer day and he would not stop talking about wanting to have sex on a ride. Talking about stories he’s heard and where the best place would be. I just kinda laughed it off I guess. I didn’t think he was serious. We got in line for the haunted mansion which used to be my favorite ride as a child. I loved all sorts of spooky things as a kid. We stood in line and he asked if I would suck his dick in the haunted mansion. I laughed in his face because I thought he was joking and was just being silly referencing the stories he told earlier. He seemed upset that I had laughed at him, as if there weren’t a bunch of children and their families standing around with us in line. I told him that it’s a stupid idea because they have cameras and I don’t want to get banned. He became withdrawn and started giving me the cold shoulder because I said no. As soon as we got on the ride he asked if he could stick his hand down my pants. I said no they have cameras like I said before. He asked again, over and over 4 or 5 times to the point where he was ruining the whole ride for me so I just said yes. He got what he wanted. I was so embarrassed and anxious someone would see. I was sexually assaulted on my favorite disneyland ride. I’ve never told a soul. We broke up soon after. Coercion is assault.
