There are three things I think should be taught to every young person, and they’re pretty simple:
1) Don’t make your life contingent on finding the right partner. Get on with it anyway.
2) Don’t swim with captive dolphins. However much fun it looks. However big their enclosure is. However many other people are doing it and saying it’s great. It’s morally equivalent to getting a wank from a slave.
3) Apply the principles behind items 1 and 2 to as many different situations as you possibly can.
