I have found this one of the few safe places to be open about my history. I hope you find the comfort and support you need.
Be in no hurry to share your story, the detail you talk of, will be very trying, at least it was for me. I was made aware last fall that my daughter (who is 35) was molested by my father when she was 7 or 8.
This has made it almost impossible to talk with her, but I will get better so it doesn't hurt her.
When I told my parents at 14, my mother asked if I liked being penetrated, I said no, it hurt, she said then you are O K. So it may not have helped if you had continued the "investigation."
We all have different stories and we all are just the same.
