Hello,
This pain during sex can be due to UTI and vaginal infection or vaginitis, a tight vaginal wall, sores at the mouth of vagina or vestibulitis, vulvodynia or a dry vagina (frictional injury), thrush or fungal infection. Pain on deep penetration is due to pelvic inflammatory disease, endometriosis, irritable bowel syndrome, pelvic tumors, cervical and uterine infections and tumors. Depending on the site of pain during penetration, diagnosis can be made.
I hope it helps. Take care and regards.
