Homeschool High isn't exempt from such behavior either. I have heard reports of orgies and other such risque behavior occurring between those "sheltered and innocent" ones of the home school class, you know the very ones who should be shocked at the mere mention of the word "sex."
I must admit that public schools can be scary places, at least in my area. At the middle school my sister attended, a girl was raped right in the classroom while class was in session. Another report was from an elementary school, a 10 year old boy sexually assaulted a 7 year old girl in the bathroom. Of course, reports of sexual crimes in school are much more disturbing to me than reports of consensual sexual activity.
There will always be teenagers who choose to act on what their raging hormones tell them to do and those who choose to deal with it and wait. (The ones in my area exercise great self control and wait until they get home from school, then use the public laundry rooms in the apartment community.)
Anyhow, if a youngster is really concerned about their inability to stand up to the peer pressure to violate something they are fully convinced is unquestionably right, I suppose they could always ask mom and dad to buy them a chastity belt.
