Summer holidays were a very fertile bullshit ground, from what I remember 
Keeping children in the dark about sex is not a good idea. Naturally children are curious so they will eventually find out on their own which I don’t recommend. I was a pregnant teen I believe due to the fact we never talked about sex in my home. I really thought that getting pregnant was not going to happen to me, even though I was having unprotected sex. I think if my mom would have been more open about sex I would not have gotten pregnant as a teen. I was uncomfortable talking about sex with my mom so I never did. Sex is not a bad thing, it is completely natural and I think parents should not let their kids feel embarrassed or ashamed to come and talk to them about sex.
Right now I’m thinking Iceland. Far enough to be hard to verify, plus coming down to summer camp makes sense.
We never talked about sex besides giving me a book, and I am certain I wouldn’t have gotten anyone pregnant, if I ever had the opportunity (I didn’t). Although with the internet, anyone can educate themselves with Wikipedia these days.
This describes 99.99% of teenagers.
Vague talk of exploits is common. “I banged that girl last night.” is fine. I could even see “I watched a great porn last night.” But the actual details, and comparing those details to real life? Well, let’s see what Jimmy says:
Oh, good. Perfect clarity and regard to reality. 
Going “Man, I’m exhausted from the 27 hours marathon sex I had just last night.” is not comparative or reality based. See the difference between an actual reality check and douche bags that brag near a water source?
There is still a heavy stigma attached to sex in the US. People find themselves in partnerships with prudes all the time. It may not be conducive to the relationship to talk about how you watch porn.
Take me, for instance. I’m technically the prude in my relationship. My wife loves going to strip clubs, both male and female. I’d never been to a strip club before I met her, mainly because I never saw the attraction. I still don’t have a particular fondness for them. But my wife wanted to go and was afraid to ask me to go with her because she didn’t want to find out I was into all sorts of Bible thumpin’ and soul savin’ or what have you.
As a person who grew up on the crusty edge of the internet in the US, I certainly did trade notable links. With particular friends. Only. Other friends were never told that I knew that women were different in any way because they were of a different cultural norm.
In the US, though, acknowledgement of that basic fact can land you in many situations that, as a teenager, you don’t want to (or can’t) deal with. You can lose friends because their parents don’t want you to ‘taint’ their innocent children with your bad influencing ways. You can get ostracized from school, if the people in the area particularly traditional. More can happen, depending on the play between multiple factors.
Well, yeah :). But Jimmy’s a jerk who only gets validation by trying to impress all of Accounts Receivable. We humor him while secretly assuming he’s got a micropenis.
I also reckon everybody also has at least a couple of *actual *friends of either or both genders they can actually be open and honest with. Or, hell, anonymous strangers on the interwebs, who are a lot more easy to be honest and open with.
Well, then I’d say they have worse and more immediate problems than wangst over their oogy bits, no ?
FWIW, I don’t get strip clubs either. Actually paying to get professionally induced blue balls ? What.
But again, if you can have sex with someone but not just *talk *about sex with that person, then y’all have issues that go above and beyond garden variety insecurity. And, all right, it might be a bad idea to mention to one’s spouse your fantasies with the horse, the lesbian twins and the bathtub filled with blackcurrant liqueur (although you might also be pleasantly surprised :p), but “Am I doing OK ? Should I be doing something different ?” is not exactly putting oneself out there.
Oh, come now. What teenager actually listens to what their parents say or want ?
Yes, but I am sure that some, if not many of these primitive cultures do not have permanent or elaborate shelters that allow privacy.
Who needs an elaborate shelter?
Us small-town kids always found it hilarious that big city teens/low-20s apparently needed to have sex in cars, since beds were easy to find for us, specially in the summer. In the spring and fall, those who couldn’t get themselves to a bed just went to a field… and in the winter many of us simply weren’t willing to take that much clothing off.
Do all those naked people now live in places without fields?
