Surprisingly few

My 2 older sisters were rather domineering and I think that made me a masochist. They frequently teased and sometimes went as far as what you could call bullying (including pinning me down or stepping on me). This happening as I went into puberty certainly had big effects on my psychology later... as I now fap to such stories.

our PE teacher did his best to pair boys with boys during class to make things less awkward as we reached middle school but it didnt always work out. One day we had a martial arts "expert" come and teach us about grappling and stuff.

That ended up with a 9 yo girl repeatedly sitting on my face or neck (close enough that I distinctly remember an unpleasant smell due to my noses proximity to her panties (she was oblivious to this)

When I reached HS, the male to female ratio returned to normal, and I had grown up enough that I was now stronger than my sisters due to biology. From then on, it was normal.
