(16F) When I was around 6-7 i was rlly sexually active and would hump my pillows (god this sounds so weird already) and my girl neighbour who was 3 years older than me came over one day and she made me lay on the bed and she got on top of me and put her hands down my pants and touched me in that area. my younger sister who is 4 years younger than me would sleep with me in bed and she would tickle me and i’d touch her genitals and she would touch mine but we were so young and didn’t know what that was but i feel so much fucking shame and i literally want to die over this thinking i hurt her in any way. is that behaviour normal in children ?? help
