We get tons of worried e-mails from readers who are dreading a visit to the doctor, so we thought we'd talk about it here.

You should see a gynecologist as soon as you start thinking about becoming sexually active (so you can talk about stuff like safe sex, birth control and preventing STDs) or when you turn 18, whichever happens first. Gynecologists can answer all your questions, talk to you about any concerns you may have and make sure that you're staying totally healthy. For those of you (like the three readers above) with questions or problems, your best bet is to let go of your embarrassment, and visit a doctor or health clinic.

If you don't already have a gyno, you can always ask your regular doctor these types of questions. He or she might answer them directly or refer you to someone else. A lot of girls are more comfortable with a female doctor, both for regular check-ups as well as gynecological exams. If you'd prefer to see a woman practitioner, let your parents know you'd like to switch to one and they can help you do that. If you don't want to approach your parents, your community may have a health clinic that provides low-cost services.

Visiting the doctor is pretty straightforward. If you let her know that this is your first gynecological exam, she and the nurse practitioner will make sure you feel comfortable. Because they see girls and women all day, every day, they won't be shocked by any question you might throw at them. Also, due to doctor-patient privilege, they have to keep your conversations confidential, so you can feel free to discuss stuff like birth control or STDs without worrying that they'll talk to your parents. To begin, the doctor will ask questions about your period, your sexual history and then do a pelvic and breast exam (neither of which hurt!).

When you have questions about your body, it's really important that you see a doctor, because diagnosis is almost impossible otherwise. That itchy feeling down below could be a yeast infection, an STD or could be from wearing tight jeans on a 90-degree day. Irregular periods could be a typical symptom of adolescence, or could be caused by a poor diet or something more serious. Only a doctor can help you figure that out. She can also check for STDs — some of which don't have any symptoms — and catch them early enough so they're easier to treat.

The best part is that once your doctor's appointment is over, you will have peace of mind. Your questions will have been answered, and you'll be able to do what is best to keep your body healthy and strong. It's a good feeling!
