I think much can be learned without actual experience. I do agree experience is a great teacher, however in the subject matter we are discussing how does this make their situation better? Relationships are a facet of life but only a facet. They can learn much just from dating their peers. I mean kids are getting pregnant.

But kids are not getting pregnant very often in nations that incorporate objective sex ed into their curricula at an early age; which emphasize the use of safe sex instead of abstinence; and make safe contraceptives readily available to them, the proper use of which are taught as part of their sex ed.

And guess what? The U.S. is pretty much the only nation in the West or North that is not doing this, but instead focusing on a heavily watered down and heavily value-inundated version of "sex ed" that is introduced relatively late to students in their lives; emphasizes abstinence, not safe sex; and makes no mention of contraceptives (let alone making condoms readily available!) except to claim they are highly unreliable when used - which is a total lie, since condoms and other medically approved contraceptives have proven at least 98% effective when used properly.

And guess what else? The U.S. has by far the highest teen pregnancy rate of any other nation in the West or North. Why doesn't it change these obviously ineffective policies? Because the pundits of the U.S. put ideology over reality; moralism over practicality; and religious beliefs over science... and yes, the Christian Right had a heavy influence on the establishment of the abstinence-emphasis policy that diluted what passes for sex education during the '80s, and they have far less political clout in any other Western or Northern nation than they do here.

So yes, there are safe ways to gain experience, and you can teach those, or you can attempt to force kids not to acquire certain types of experience, which... doesn't work, because the only thing that happens when you do that is you get a society full of kids doing the same things they would do in a more liberated society, but sans the education, access to information, and benevolent guidance that would enable them to make these decisions in a far more informed manner with the liberation-based alternative.
