It is recommended that first visits to the gynecologist start around age 21:
This recommendation is the same whether or not you are or have been sexually active. That means if you are 21 and not having sex, or if you are in a same sex relationship, or if you are transgender but still have your cervix, you should go to the gynecologist. It also means that even if you are having sex, most young women do not need to go before the age of 21. Personally, I think it is helpful to meet a gynecologist once you are sexually active, but a lot of young women are scared to go and then start having sex without birth control or STD prevention. You can get birth control without visiting a gynecologist. Make sure you protect yourself against infections and unwanted pregnancy if you decide to have sex!
What exactly happens when you go visit the gynecologist:
She will ask you about your medical history, sexual history, medications you are taking, what concerns you have, what your period pattern is like, and similar questions. Often you will fillout a form with a lot of these questions, and then she can go over it with you.
You will be given a gown and told to undress completely underneath and then tie the gown in the front (like a robe). She will step out for you to change and then come back to examine you. You will get your weight and your blood pressure checked (perhaps by one of the nurses). Then you will sit up on the exam table. The exam table looks like this:
She will use lubricant or water to make the speculum and insert it gently. When it is inside (not the whole thing, just the part on the right that looks like a closed duck bill!) she will gently open it so that she can see inside. She will do a pap smear with a small plastic tool and may take other samples for infection with cotton swabs. She then will insert one or two fingers into your vagina to examine for lumps and bumps inside your pelvis and for any pain. Depending on what your situation is, she may also insert a finger in your anus to look for similar problems.
What exactly is a pap smear?
A pap smear is a gentle scraping of the cells off your cervix to look for cancer or HPV changes. This is a picture of what the lab looks at for a pap smear:
Well, I hope that answers your question and also sheds some light on exactly what happens when you go to the gyno.
