My boyfriend's brother saw me naked in the shower?

I was at my boyfriend's house and his brother accidentally walked in on me while I was taking a shower. He apologized for it and it hasn't happened since. But, he did tell me not to tell his brother because he thought the brother would be mad at him. And I said OK. I never mentioned it to my boyfriend because I felt that he wouldn't want to be with me anymore if I told him and would no longer want me at his house. What should I do? Should I tell my boyfriend or not? This incident happened in the summer of 2024 and his brother felt really embarrassed by it. Help me someone!!!
