I'm 18 and I never thought I would make the mistake of having unprotected sex and thinking I would be okay. I ended up being tested positive for Chlamydia. It might be uncomfortable to talk to anybody about but if you just keep it to yourself like I did, it will make everyone you love and care about very upset with you. So always be safe and get tested if you feel like something is wrong. Because I had no symptoms and if I didn't get tested sooner it could have been way worse and maybe untreatable.
