Experience is the best teacher #4: When you cannot let them actually experience something

No, you cannot set up a situation where they can learn about intercourse through experience. So what do you do:

• Simulations and role plays (not role playing sex, of course). They can be on how to handle situations or what can come from an event.
• Personal stories. Not your own, or at least de-personalized. The experience of public figures can also be helpful.
• Data. Statistics. Not the most effective, but when combined with personal examples can get their attention.
