When I was in HS, no one was encouraged to explore their sexuality in any way.   But I would agree that measures to protect and educate young people about sexuality is a good thing.   No one wants young people to experience alienation, no one wants suicides.

On the other hand, I do think every young person should be encouraged to be heterosexual.  And along with that, a recognition that we still don't know much about human sexuality, especially how it's formed. 

The flip side of that would be to encourage all young people to be whatever they feel like being -- creating conditions where they may be coerced by ss attracted people in their group to ss acts.

At least one thing good has come from the Catholic sex abuse scandal -- so many of the abusers of children have reported they were abused themselves at a tender age.   This has to mean that ss activity while young can have lasting effects on a person's sexual formation.
