The risk of an unwanted pregnancy which could alter your educational or career plans is real. The risk of contracting a sexually transmitted disease which could threaten your health, if not your life, is real. Abstinence is the only completely safe behavior and is, therefore, something you should feel good about. It's important to realize that it's never too late to choose abstinence. Even if you've had sexual intercourse in the past, you can choose not to continue this practice in the future.
Teens face a lot of pressure to have sex.
If abstinence is your choice, you need to think about the sources of that pressure and how to avoid or resist it. Under the right circumstances, sexual passion may override your best intentions. Those circumstances may be as innocent and ordinary as time alone with the person you are in love with. The best way to avoid stumbling into sex is to make sure you are adequately prepared. Anticipate the circumstances you may find yourself in and rehearse what you will say and do.
