That was a long read, Catherina. But totally worth it.
I’m sorry to read about your abusive childhood. How wonderful that being naked helped you cope with it.
But the “urge” was not caused by that. It was already in you.
I dare to say this, because I totally recognize your description of it. Even though I came from a loving family.
I had the “urge” to be naked already as a child. Secretly of course. But I practiced it sometimes anyway.
The scenes at the pond or outside your house are familiar.
The desire to be nude is like breathing. You can postpone it for some time, but not too long.
It took me decades to turn this from a “quirk” to an integrated part of my life.
