The easiest way to catch an STI is by having sexual intercourse without a condom. Learn how to put one on and, if you are having sex, use it. The other way to avoid STI's is to not have sex at all. You don't have to!

If you think you might have come into contact with an STI it's important to get treatment as soon as possible. Don't wait until any symptoms have time to clear up. Even if they do you will still have the infection. Most STI's are easliy treated if discovered early on.
