Yeah...so sex and children. Really I'm not sure why this topic should be suppressed any more than anything else. I'll default to my usual rant about parental involvement. If you leave your kids to their own devices but yell at them for watching porn, all they'll ever learn about sex is what they see in televised advertisements. And that's really bad, to say the least. On the other hand, if you tell them from an early age what sex is and how reproduction works, it seems like it would demystify sex. But I don't think that a single talk (i.e. "the talk") is enough. When you're talking to your kids about how to read or do multiplication you don't have a single talk. In this regard why should sex be any different?
Regarding this talk of traumatizing kids, the exposure to rape scenes is an important example. I'm no child psychologist either, but I'm pretty sure that here the mental trauma comes from the violence and not the sex. I've got a couple friends with a three year old, and on those rare occasions when he sees violence on TV he's pretty visibly disturbed. Kids seem to know that something is wrong with violence, and I can see how it can mess you up if you see it too much. Heck, adults aren't that different, a lot of Iraq vets seem to have the same problem. But again, I don't think this is the same thing as being exposed to sex. Here's an interesting fact: in Canada you can show naked men/women on TV. Once when I was at my cousin's house up there I asked him why they let broadcasters do this. He said "well we think it's pretty stupid that you ban sex on TV but let people watch all the violence they want." If anything we should have these taboos about violence, not sex.
I never had "the talk" -- I learned about it from watching porn on late night HBO while everyone else was asleep. So, yeah, it's not that "scarey" or traumatizing if you're old enough to process what's going on.
My parents and I never had the talk either, they just let the school deal with it. And as you can all see, I turned out perfectly normal. Or not, since I like female breasts about ten times more than the average healthy male. Maybe they should have brought topless women into sex ed and let me feel their breasts for an hour a day, then I'd have gotten it out of my system early on.
Oh and yeah, I remember that late night squiggly line HBO porn too. Funny thing is that now as an adult, I
have HBO and I never watch their porn shows. My DVR's too full with Game of Thrones.
