sexual abuse?

disclaimer: my brother has autism

when I was young, between the ages of 6-8, my older brother who is 4 years older than me, would want me to touch his 🍆 and he would want to look at me. one time he thought I would grow a 🍆 .

one time he made me take a toy stick and put it in his butt cause it felt good. he did the same to me even though I said no.

I never really knew what all this was, and my family hushed it up and contributed it to my brother having autism. we weren’t allowed to be alone together for years. I still don’t let him hug me, I’m 21 now.

was what happened sexual abuse?
