It is not normal nor acceptable for any woman to have pain and burning urination after each intercourse. Initial few intercourses may cause such feeling as the vagina is yet very tight and the hymen may be present. However, after many intercourses, hurting feeling in the vagina and burning urination has to be taken cognisance of. It is a good news that your doctor has declared that you are not having STD. The most possible cause I can see is dry intercourse. May be he is inserting his penis in your vagina in hurry while the vagina is still dry and you have not become wet. This can hurt the vagina from inside and even the vulva outside causing the discomforts you are experiencing. Try two things: 1. Wait for the insertion till you are absolutely wet. Then naturally you will have an urge of having penis inserted. Let him insert only after this when you DEMAND insertion. 2. Use lubricants. Please avoid oil-based lubricants as they are dangerous to the women s internal organs of reproduction - particularly mouth of uterus. Use only water-based lubricants available in the pharmacy shops. Vaginal jellies are also good lubricants. If he is using condom, please ask him to insert under vision directly inside the vagina without touching outside parts, particularly the urinary opening. The latex rubber of condom does cause inflammation of the urinary opening, later on leading to infection. Remember, size of the penis will not hurt vagina. Much larger head of the baby also is accommodated through vagina without trauma. Sex is a delicate game. Do it gently and artistically. I am sure you will enjoy your long life full of sex.
