No they will only check for STD's if you ask them to they never do just on a checkup for something else. The doctor will probably tell you to go to the clinic or county health department to get checked and tell you they don't do it at the hospital. Most clinics don't tell your parents so just go up there and get checked, they are very confidental about it. I am serious though you really need to go. It didn't hurt to get a swab stuck up my penis it just felt like a little sting like a sting you feel when you get your blood drawn from your arm. I won't get my results back until this Wednesday. Everytime I get a new girlfriend I am going to have them get checked first and I will to so that it will be fair even though I know I won't have any.
