Sexual shit in shonen media

I was considering getting a manga volume as a gift for a cousin but literally all the ones I hear are for kids and start reading(naruto, dragonball z) have ecchi sequences right in chapter 1 are Jap kids just extra perverted or is the culture different local kids media barely has any romcom stuff and even in American media at most you'll have light romcom. When I used to watch anime on TV I'd flip to cartoon network every time stuff like that happened cause my grandparents would be nearby He's 10 BTW, it'd probably not be very shocking to a kid with internet access but I don't like optics of his parents maybe flipping a few pages and seeing a naked(appropriately blurred) lady.
