is this "normal" behaviour for a child

i remembered from a young age i was very interested in sex i am a female and i had a male friend and his mother used to let me and my other female friend bath him i must have been like 5-8 yrs old and i would touch his penis.not sure how old he was
also me and a male friends used to experiment touching each other.
when i was maybe 6 or 7 or even younger i used to masturbate in front of my niece who was 3 yrs younger than me and a couple of times we kissed and once i went down on her. i had some other sexual experiences with other friends. all i can really remember is i was soo young. surely that cant be normal for a child that age to be interested in all this, i have never been abused as a child to my knowledge and my parents were not open about sex and i cant remember ever having the talk.
i'd be grateful if anyone has any opinions on this, as i find it strange to be so active at a young age when i had never been introduced to it. i dont know what made me interested in it

thanks for reading

I think its normal to touch. Show me yours i will so you mine. The way my therapist says. Accept I went down on someone as well when I was about 7. She said this is not normal. Either i was sexually abused, watched porn or another child showed me that, or saw my parents doing that. It is a learned behavior.

thanks for your reply, yeah i was thinking there was maybe more to it, but i doubt i had access to porn at that age and probably didnt know what porn was at that age etc and i have no recollection of being abused, so i really dont know, the person i went down on told her mam so she told mine and i remember her asking who showed you how to do that and i remember saying no one and she kept asking so i just said my friend. but i cant remember anyone every showing me that etc, maybe ive totally blocked it out or it was just a kid thing i somehow knew about

I agree with Dnester, curiosity at that age is completely normal. Some masterbation in front of other children can be normal, for example if the child is too young to understand what they're really doing, and simply sees it as, when I do this, it feels funny. But a parent should then explain that this stuff should be a private thing.

As for "going down" on another child this isn't normal at all, it's definitely learned behaviour. I don't know where you are from but in the uk we have a helpful website on what is normal sexual behaviour in children between ages 0-16 take a look:
