There are enough things that children/teens must be sheltered from. Don’t shelter them from things that are not necessary. It will just make it harder for them to deal with when they are confronted with the issue.
It reminds me of a joke about a father who never let his son see a girl. One time they were outside and the son saw a girl. He asked his father, “What is that?”
His father answered, “A katchka (chicken)”
The son said, “Ah, what a nice Katchka!”
