Um, okay. Well, this is where cultural differences come into play. In Finland, at least when I was a kid, and I don't think that's changed too much: no-one cares about 1-5 year olds seeing naked women, and that goes for 6-8-(or generally surely before puberty) ages, if it's like family/friends gatherings; sauna, and so on.
Then, at puberty, 12-13 and from there, females are generally the only thing in a teenager boy's mind. At least they were from me. And during that time, boobs and the vagina become like the holy grail. Then it kind of depends on the kid, whether he manages to find similarly hormonally-crazy girls who are willing to explore and share experiences in that area. I had my fair share of plenty of magnificent breasts during the teenage years. So it was merely the very beginning of puberty, when the wonders of women's breasts were hidden from me. And before teens, I didn't really care for them.
So I can't really see the point. Nudity isn't as much of a taboo here.
