Did I commit child on child cocsa

Recently I’ve been dealing with so much guilt and shame and i feel stuck with so much thoughts from sexual experiences i had with family members. From ages 6-14 to when i was younger me and my cousin same age would play dolls my little sister as well around 7-8 me and my little sister she 3 years younger would sometimes play inappropriately with the dolls too we also would hump each other not everyday but blue moon. Around 9 when i moved my brother had introduced me and my cousins to porn and would practiced what we saw one time he performed oral on me and i didn’t think much just that it felt fun but felt secretive which means he abused me also being he was doing stuff even tho i didn’t want to at times. When i was around 10 thats when things ended between me and my brother. When i was around that age me my sister and nephew would play toys all the time and one time me and my nephew and sister would all hump each other we would wrestle or sometimes piggy back rides and one time it led to my nephew licking my bum area and i asked if he wanted me to lick his area he said no so we started playing toys again one day it was me and my sister and nephew they started humping and i was letting it go on and my nephew dad walked in we all hid because he look upset. We wouldn’t see eachother as much then we moved into a house together and we hump eachother still until i was also i was being groomed by an 23 year old man at 12 but the stuff that occurred ended when i turned 14 i stopped because i felt gross and started to develop more compared to them and also around 12 me and my sister would watch porn and sometimes she would ask if i could touch her areas and i would touch and lick her down there . We would also look at my older sister sex toys and would play with them while they were at work . And stopped ofc because it felt wrong now everyday i feel like i cocsa them and i feel sick to the stomach that we did all that i feel like a perpetrator ive talked to my siblings to make sure i didn’t traumatize or hurt them they said we were being nasty and curiosity it was inappropriate and we stopped once we realized that. I feel so sad i feel like i preformed cocsa idk what to do i wish it never happened my sister and nephew and cousin we get along very well. They told me to let go im scared when we get older they will think of me as a molester or abuser i always wanted to become a teacher and help people out i feel like i don’t deserve that.
