After losing virginity, is it normal to feel a weird need to pee during the hours after? (even right after peeing) + a little disconfort and burning while urinating? also more gases than usual? (diet did not change at all before or after intercourse)

U need antibiotics: I suspect what you are experiencing is called a honeymoon cystitis. I doesn't have anything to do with the loss of your virginity as much as it is about sex. Some women get a bladder infections after sex. Vaginal intercourse makes it easier for bacteria to enter the bladder through the urethra. Women who use diaphragms, condoms & spermicides also have an increased risk of UTI after sex. See a doc.
