Salut ! I have never heard of any link between masturbation and DPDR. But there is definitely a strong link between DPDR and anxiety, this is for sure. It sounds like you are going through a shitload of stress, and I know that these "classes prépas" are really hard, almost like an abusive experience. I had a colleague who went into deep depression because such a school, and today I was just listening to a woman online who made a suicide attempt because of a serious burnout during the same thing. All of this is really hard.
I have been stressed about potential sexual problems for a while, it happened like around 15, and it did feel like my whole world was collapsing, because I thought this could affect my future sexuality, or I thought, my ability to be in a relationship. It turns out that for me it was absolutely not the case, what I thought was a sexual problem is something real but it never was an actual problem and I have never met a girl/woman who cared a single bit about it. But still, that anxiety was there for real.
You might have had a look at the recovery stories here already, I think there are a lot of experiences of people who suffered with anxiety or panic attacks, and for a lot of these people, their DPDR symptoms subsided when they solved their anxiety or panic attacks. If you are like most of them, it means you might find some relief by just focusing on solving the anxiety problem and all your DPDR symptoms could go away without you having to do anything about them directly. DPDR symptoms are weird and they can easily put people in an anxiety loop, because they feel crazy, they feel impossible to understand, and people feel they should figure them out in order to fix them. But this is all part of the symptoms as well, and fortunately there is no need to "find the way out of the maze". The maze usually dissolve when people find a way to treat their anxiety.
Have you ever been to therapy for that? I heard that cognitive behavioral therapy works really well for a lot of people dealing with anxiety, (and psychoanalysis only usually doesn't - I'm saying that because there are still a lot of psychoanalysts in France).
