Okay so I'm only 15 years old and I want to get a blood test because I'm worried that I might have STD (herpes/cold sores) from doing oral sex with my bf. But I don't know what to do because I don't know how to approach a doctor since I don't want to go to the doctor with my parents (I don't want them to find out I'm not a virgin anymore, they might kill me.) plus, I don't have that much money to pay for the blood test. what should I do now? please help.
