As a teenager, you pretty much have a mind of your own, of what and how you'd like things to be.
Teens should be educated on the value of saving sex for marriage and that every life is precious, including those of the unborn. They should also be made aware of the dangers and ill-effects of viewing pornography.
You are precious and therefore worth the wait - most teenagers who've had premarital sex regret it later, so save sex for the best - marriage!
It's perfectly possible to have romantic attractions without sexual expectations. In fact, it's even better as you won't have to worry about the consequences of premarital sex.
It may never have been openly discussed, but pornography is a big issue with lifelong implications. Avoid it at all costs, but if you've engaged in it, get help!
