I don't know that my early teens were dating or having much "experience" with sexuality at that age? Puberty is just starting and all sorts of hormones and changes are going on. I guess I'd discuss it with them, where their thinking was coming from, etc. But I wouldn't particularly worry about it until they were older teens and choosing who to hang with on their own (could drive or go out with others with vehicles, etc.). I wouldn't do much different one way or another at that age, would kind of wait to see what developed over time.

It reminds me a little of cousins/nieces/daughters, etc. who have gone through a vegetarian "phase" after reading Charlotte's Web or have tried different eating habits, etc.
