I'll start. When I was like 7 or 8, middle aged men sent me pictures of their dicks. Fun, very spicy and traumatic. Oh, and back in 7th grade, a man tried to touch my chest in publice transport. :) Idk there's probably more, I'm too lazy to remember.
one time we were all on the playground with tons of kids and mothers and most of my friends were boys and suddenly screamed yamete kudasai (in a erotic way)and most of the moms look at us it was so awkward reply
