Will I be punished somehow by the police?

Okay just a few hours ago I was leaving my house in my stepdads Honda shadow (motorcycle) and I was going up a hill at the speed limit or 15 mph I believe I don't recall. The lane is a 2 way one going up and one coming down. As I was going up the hill a car (who had a stop sign) jumped in front of me and when he saw me he stopped sudendly and I had no time to react. I did press both breaks on the bike and down shifted if I wouldn't have done that I would of died probably. The only thing that hit the car was my front tire and it dented his car door. Not too much but you could see it. After that we argued about whose fault it was and I know for a fact it was his. He had a stop sign and this bike is pretty damn loud and he just went for it he said I was blocked by cars parked. But if you can't see when you're on a stop sign don't you have to come out little by little until you are clear to see? But again he just launched and It didn't give me reaction time to fully stop. Now after that he got in his car and I left the. He followed me honking at me saying we have to report it. So I stopped and I told him you understand it was your fault because frankly it was. He's the one who suffered jumping out blindly luckily I had time to break because I wasn't going that fast and so after that I just left and he got in his car. Now my question is… If he reports it somehow will I get punished? Any suggestions to this problem. I'm leaving for marine boot camp in about 15 days. Help
