You need to see a gynaecologist your relationship and mental health will suffer if you don't go, also if you have this pain every time you have sex you will eventually begin to fear sex through association, painful sex is not normal but not uncommon. With luv.

What would a gyno actually do?
I've never been to one, so I don't actually know where my local one is.
Its been a problem for at least a few years now

Take your medical history, then do a physical examination, take a few swabs to check for localised infections. Don't worry they will be very gentle and understanding , you may be able to choose a female gynecologist if you think you might feel more comfortable. What ever else happens she will treat your problem and let you and your partner get on with your life. Please do this . With luv.

How do you treat something like this?
And won't the swabbing involve them inserting something?

The swabs are almost unnoticeable and you can ask for a local topical anaesthetic to be used if necessary, the treatment could range from a course of antibiotics , to surgery depending whats wrong. Go do it -it won't go away on it's own.

Sorry about so many questions.
If I went to a gum clinic would they help?
Is that a gyno?
Or going to speak to a nurse at one of them local sexual health clinic things?

I've put off doing anything about it for ages, but its becoming too much now.
Im thinking the problem may be psychological.

I found out I have hpv becuse I was having pain during entercorse and I want to the obgyn

Whats that?
Do you think thats what could be causing the problem?

A swab is extremely small; however you should probably have a full pelvic exam since you are sexually active, no matter what your age is.

Pap-smears are not frightening; they don't take long, and there is so much that can be learned from them.

Going to a doctor, a gynecologist, is a very important thing to do! Please go get a first check up now that you are sexually active! You need to keep yourself healthy.

Planned parenthood is a clinic that will do free exams and dispension of pills and other forms of birth control for women with low enough money, or if you are a student.

Thanks for all your help!

Just another thought ; depending on your diagnosis, should your problem be caused by an infection it may be necessary for your partner to under go some treatment to prevent reinfection, ask the doctor.
