Most kids figure out how to masturbate as toddlers and then are told to knock it the fuck off by parents. Because it's merely a "this feels good" thing and not a hormonal thing, there's really no reason to disobey until later. The Freudian "Latency" stage exists, but it's purely sociologically created.
But everything feels the same before puberty; all the nerves are already there and working. I stuck stuff up my butt because it felt good. Can't explain it any better than that. And seeing other boys naked gave me a boner (among other things) so… yeah. It was what it was.

Nothing in the body is "clean". But it's not shit, and it doesn't smell bad (a little bit musky, kinda like sweat and cum mixed together, I guess?) and has basically no taste. It's like clear snot, except in your ass.
