Hello Willhelm, and welcome to the company of experiences and shared understanding. All of us have had various experiences, and I am not sure if I can recall a 69, I won't say it didn't happen, I'm rather unmotivated to go into the near same age molestation time of myself at present. If at some point I recall during EMDR, that might reveal. I'm not too upset for now, I've plenty to deal with. *Trigger warning* Younger days led me into the hands of at least 2 boys self-will and with a very deep unknown, an adult pedophile might have abused me once? I don't know, it's been a very, very long dream-like thing. Again, it's not been too important yet.
Nothing I'm posting is to diminish your memory or need to be aware of your memories, it's pointing to where I've needed to be, and the memories I've had all along, very suppressed by me, but now finally pushing into my life, they're the part of me needing a lot of work. I hope that makes sense? I often doubt I'm saying things clear, or making it worded the right way. Some give me feedback of understanding, but my doubt has a long standing record of overshadowing my thoughts.
There's nothing wrong with doubting a memory, or thinking about it in such a way that you've decided it's true, but have a nagging doubt. That's Okay, our brains in PTSD have issues like this, and memory is one of those issues. Some therapies might help with it, or some things done for memory recall might work. I don't endorse some things, and that's because I've never done them, and/or, it seems in my experiences and reading I'm less inclined to look at a therapy I'm unsure is in the category of "therapy". I don't want to state what I might consider in any case, except those of my experience. My projecting onto anything like a therapy, might diminish your journey if it includes that. We're all different, and I'm keenly aware of my difference.
My mind will go many direction while I write this, but my hope is that you'll know, the trauma is well known here at MS. Here, among men who know, most Ok with the word survivor, and looking at this from semantic self positioning of words, one may look at the equality of healing and recovery words, and mingle them. I'm of 12 step recovery, and lifelong need to heal for this newly revealed PTSD. I think in healing, I can recover things about myself, and that will be great. In fact, I'm doing EMDR finally. I recovered my 12 year old self at the worst point of him being bullied. This was only this past Monday and I wrote a very long post about it. It was intense and gratifying. That kind of healing event, where I've recovered something taken from me by bullies, left unprocessed for 43+ years, is a gift. Now, I'm looking at those particular events and my 12 year old is safely looking at them through my adult eyes. He's feeling the security of me, the need of my adult self to make sure he's going to get through that extraordinarily damaging part of our life.
So, to conclude my verbosity, there's hope, there are lots of things to discover and find, and so many of them will help your healing journey. You can recover many things of yourself in time.
Best wishes.
