My cousins (who were practically siblings) were a few years younger than me and were in a similar situation. A few years ago, my male cousin told me they'd all, at like age 12-14, watch each other pee and poke each other in the vag/penis with twigs. It was some form of pre-internet "haha it's funny also look, vagina and penis" thing, not sexual, and it never went beyond that but still...thank fuck I wasn't involved in it. Even in a wholesome family environment shit can get weird. And we were pretty well supervised.
