This isn’t one of the memories that regularly plagues me...
I only recently remembered it again
Very unpleasant .... understatement
My “first kiss”
Possible trigger:
It was at a neighbourhood party. I had just turned 16. I was at a (horrible) all girls school and had been “protected” from “boys” and not allowed to go to youth clubs etc...
I was also a “late developer”

and the (few) friends I had were mostly also similar
My “first kiss” was at this neighbourhood party. It was a horrible, unknown to me, man, probably well over 50. He went up to me, kissed me, and pushed his tongue into my mouth
The bear cub.
The “ugly duckling”

Blamed
Hated
Violated

I didn’t tell anyone.
If I had told the parental units I would have been blamed for “leading him on”
