This Is A Gynocological Question. I Am 52 Never Had

This is a gynocological question. I am 52 never had children and have been single for many years. I do not
have an active sex life. I have been menopausal for many years and my period stopped completely Dec 2015. I recently had sexual intercourse for the first time in 12 months and it was very painful. I have never experienced this type of pain before during intercourse even during long periods without sex. The pain did not persist after sex and there is no pain or burning on urination.
