Is my past going to ruin my future?

I need your thoughts. So my boyfriend that loves me so much and that I love so much is going to a tournament with his team and the people he is staying in a hotel room with are two guys that in my past which I'm not proud of have messed around with but not sex. I know that they're going to talk shit about me to him so I told my boyfriend everything I had done with them so he wouldn't have to find out from them. I'm so scared that they are going to talk about things and upset my boyfriend. I just hope I did the right thing by telling him but anything else that happens is just out of my hands. Any advice or thoughts on the situation are appreciated.
