When I was younger, I was sexually abused which lead to me sexually abusing others, what will happen if I talk about this in therapy?

I'm on a throwaway for obvious reasons. I do not want my post being on any websites or videos.

A family member of mine abused me sexually and physically through the ages 8-16. During around the age of 10 to 12, I regretfully confess, I sexually abused a child who was asleep, he was 8. I touched him and he never woke up, but I feel gross and disgusting. I dont know why I did it. There was a time a friend slept over, and I groped her breasts while she slept. We were 11. She never woke up either. I also touched another family member, but we were awake and they were younger by a couple years.

I've been in therapy for two years now, and I'm trying to grow and heal. I'm trying to deal and accept what happened to me with the family member who did this to me. I want to bring up in therapy what I did, but truthfully, I'm scared.

Do I need to prepare myself to be reported to the police? Will I be charged? Is it something I should talk about in therapy? I really want to. This has been eating away at me for years. If there are consequences to my past actions, I want to take accountability. I want to know what to expect.

Thank you in advance

Edit: I am a female

Edit 2: I know I don't need to update, but I thought I would. I had my appointment. Right away, I asked hypothetically what I had typed here.

My therapist was amazing. Right away, she told me I wasn't disgusting. I wasn't a predator. I was an innocent child who experienced sexual abuse and neglect from the protecters in my life. When these things happen to children and they don't understand, they're curious. They end up doing the same actions because that's what kids do.

I expected this answer from her due to the comments. It helped a lot that she went into a lot more detail and continued to assure me it wasn't my fault. She told me I have to forgive myself.

I feel as if a weight has been lifted off my heart. I dont truly forgive myself yet, and I still have a lot of emotions and thoughts to process. The self hatred isnt as bad as it was when I first started therapy. With the help of therapy, it'll be okay. Im truly sorry for what I did, and I truly hope the victims were asleep. I hope they didn't get woken up to what I was doing for their sake. As for the victim who was awake, I hope he is doing well and is healing.

Thank you again to everyone who gave me advice.

Take care
