Was it rape?

So some of you probably read my last post about me and the girls who sexually assaulted me in the 3rd grade at the boys and girls club.. the following school year my parents decided to stop paying for my membership there and allowed me to ride the bus home instead.

4th grade year my parents were very involved in the gym so often they would leave my brother (6th grade at the time) and I at home alone. I can't really remember how it started, I just remember bits and pieces due to me trying to forget it for so long. I remember one day he made me recreate a scene from P⭐️rn with him. I remember one day he made me bend over in the dryer while he did me. I remember one day I was in the shower and he came in there and did me. This all lasted until the summer leading into my 6th grade year ( so 1 1/2 years) because that summer is when I got my first period. I'm sure he realized he was wrong because at the time it started I was 9 he was 12 and when it ended I was 11 he was 14 (he's 2 1/2 years older). But I often wonder if I was in the wrong as well .. because I let it happen and didn't tell anyone until my 10th grade year, his senior year.
