When covering sexually transmitted diseases, some educators like to intentionally scare the pants off you (no pun intended). We believe the facts speak for themselves. 4 million teens will get an STD each year. To help you avoid making this list, we've put together some invaluable information. If you do ever notice unusual secretions, bumps, blisters, warts, pain in the abdomen, intense genital itching or tiny spots of blood on your underwear, see a medical doctor right away. The sooner you're treated the better. No STD just disappears without treatment. Many go into hiding, and then show up a couple years later, along with more serious symptoms such as severe organ damage and/or sterility. So if you've had unprotected sex, ask for STD tests during your next yearly physical. If you notice symptoms of STD, see a physician immediately! Most states allow teens 12 and older to get confidential diagnosis and treatment. If you unfortunately do discover that you have an STD, your parents may need to know in case you contracted the disease during birth.
