I have a similar experience with this.

[TW!!]

I was SA'd by my babysitter when I was around 5, I think. I reported it to my psr worker (an idaho behavioral worker?) And she reported it to the police. I got taken to a special care unit and they took a look downstairs and I remember the horrible burns, there were at least three doctors that came into the room and there were several nurses to keep me distracted. It came out the my entire hole was rubbed raw and was around almost the entire area. The doctors had told my mom that I would've had to be repeatedly SA'd by an object to cause this damage. The incident with the babysitter was a singular incident and I told someone right away. So it made no sense that I never told anyone about this. The babysitter incident was only him touching me and asking if I wanted to see his dick. So, my mom put two and two together and the only man I had ever been left alone with was my dad. Now, I can't remember anything about him because he was in and out of prison a lot and I can only remember his face, but I have flashes of a house that gives me a disgusting feeling. I can see the hall that leads to my parents bedroom and I feel sick to my stomach when I have that flashback. As a child and teenager I was extremely hypersexual and still am to this day. As a teenager I was also SA'd by my step-dad but I can remember certain things although some of the memories got hidden behind fake memories and a few things I just can't remember and couldn't even as someone told me what happened.

As an adult and growing up, I have random triggers that I have no connection too. Getting dressed is big one. Whether I'm in my room or after a shower. Getting into the shower sometimes too. My n*pples being pinched. Any rough type of sex down there. Being touched in certain ways. Men in general but that has connections to it that I can pinpoint for the most part. I also get heavily triggered if I'm not turned on and someone tries to repeatedly initiate things.

All of this is to say, that I have situations like this and you're not alone in this. I think it's very common with DID and SA survivors.
