My GOD. Opening your sisters legs and putting your face in her skirt is different from accidentally looking at someone's private parts in the change room.
This isn't abuse though. Abuse is when my sister told me to have a shower in a room with no locks so she could film me naked coming out of the shower and show our entire family while I was already a depressed and self hating 9 year old. It's obviously not nearly the same as being raped but it was still emotionally abusive.. And when I called my sister out for bullying me my entire childhood this summer she said 'That's what siblings do'
