tw for possible sexual abuse

uhh this is kinda embarrassing to ask on here and i lowkey feel like this is just undermining actual sexual abuse so call me out if im wrong

so when i was about 8 and my sister was 10, she would kinda like,,, forcibly kiss me? like sometimes she'd pin me against the wall and start humping me(pls dont say "sweet home alabama" or something in the replies because writing this by itself is giving me bad memories and im looking for help). she kept forcing me to kiss her sometimes when i was trying to fall asleep even when i told her to stop. she'd also force me to watch porn together(it was out of interest at first but when i said i didnt want to watch it anymore, she still forced me to look at it).

and another incident was when i was with my aunt and my mom getting my hair done when i was, i think in 1st-3rd grade. my memories of this are really blurry but there was this guy who would keep touching me there and i didnt really know what was happening so i didnt do anything lol
nothing much happened but he put his hands on my stomach and touched my ass a little bit. i dint remember how old he was but his voice was kind of deep so im assuming he was atleast in 7th grade.

i mentioned this to my friend a few months ago and i guess i kind of thought it was normal? but then they said it was sexual abuse so i was just?? and its been on my mind ever since. uhh just tell me what yall think ab this cuz idk lmao
