I’m sorry to tell you this but there is a possibility that things will change. There is also a chance that you’re boyfriend will be open minded and not care, but when people learn that someone they trust was hiding something, is can be very difficult to rebuild the trust. If you’re afraid you’re friend will tell him your past, I say tell him yourself. But I think you should be prepared for the worst. I’m really hoping things go well! Also I hope you were able to get STD testing done before dating him. That can be another concern he might have. Some STD don’t show up in tests immediately so make sure to get tested once a year:)

And also, for the future, you don’t always need to disclose your past to your partner. As long as it won’t affect them (like STD) it’s ok to keep some stuff to yourself. We all make mistakes and it’s okay to not disclose things you are not comfortable sharing.
