I feel like such a monster. I wish I could get over this obsession but it seems to always be at the back of my mind. I know sexual experimentation is normal as a child, but what I did, I think goes beyond that. I was 10, and I put my little sister’s hand on my breast while she was sleeping. For my own sexual gain or curiosity, I don’t even know at this point. I don’t think I can ever let myself live this down. I’m so disgusting and terrible and I wish I could erase what I’ve done, I really do.

Kids do a bunch of weird things when they are learning. Be gentle with yourself.

Everyone has made unfortunate choices. Most people can understand that, repent if they are religious, and move on. You have OCD, so the current problem is not what you did, but how you think about it. Its important at this stage to identify- what does my OCD want me to do? And then to not do it. http://www.ocdspecialists.com/real-event-ocd/ This article can help. Try to refrain from googling for similar experiences, or from wallowing in the guilt, or from playing over the event. A good mini-script would be "I notice I'm remembering the time I put my sister's hand on my breast. Maybe that says something about who I am today. Maybe it doesn't. I am choosing to be uncertain and to focus on the task at hand"

I used to have a similar theme. While it might feel like you have to tell her to be a moral person, this is a sneaky compulsion and you must avoid it. I made a deal with myself that I would never talk to my husband about details of my OCD themes for this reason. It becomes compulsive so easily.

You were ten years old. I know it probably feels like you're a monster, but OCD has a way of blowing things out of proportion. When kids are discovering their bodies they tend to get up to a lot of weird, taboo shit. When I was seven I masturbated in front of family members, without knowing what I was doing or why it was wrong. Children just don't have the mental capacity to understand those things yet, because they don't have experience. Maybe think of it this way: if you saw a young child doing that, as a parent, you would scold them, but it wouldn't make you think they were a terrible person for the rest of their lives. You would realize they were just a kid and forget about it sooner or later. I find that a good method is to ask, how would I feel if I were on the outside looking in as an objective third party?
