Hi, Based from the information provided, you do not have any STD and you had your gynecological exam before 3 weeks and nothing was found wrong / abnormal. So from that point it seems to be a psychological issue like vaginismus. Common symptoms of vaginismus : 1) Burning or stinging with tightness during sex 2) Difficult or impossible penetration, entry pain, uncomfortable insertion of penis 3) Ongoing sexual discomfort or pain following childbirth, yeast/urinary infections, STDs, IC, hysterectomy, cancer and surgeries, rape, menopause, or other issues Ongoing sexual pain of unknown origin, with no apparent cause 4) Difficulty inserting tampons or undergoing a pelvic/gynecological exam 5) Spasms in other body muscle groups (legs, lower back, etc.) and/or halted breathing during attempts at intercourse 6) Avoidance of sex due to pain and/or failure. Treatment in case of severs problems are (1) Dilation done by gynec , (2) Trying relaxation methods. ---------------------------------------------------------------------------------------------- This may explain the roughness which you are trying to say, it can be a swelling due to friction caused due to dryness. Best way to deal with the such an issues is to use some lubrication. Hope it helps. Dr. JAY PATEL.
