I totally sympathize with your situation.

Ever since I became sexually active, I have experienced pain during sex, and it has developed as I have aged.

I became so upset and frustrated with the pain that I went to see my doctor about it. She referred me to the hospital to see a gynecologist, who eventually diagnosed me with endometriosis. My advice is for you to see your general practitioner, keep explaining the pain, and ask for further procedures, if you want them.

I know it is embarrassing, but it is better to know so you can deal with whatever is causing you pain.
