On and off for a couple of months now after my husband and I have sex my vagina would get swollen, irrated, and red. I thought maybe it was becasue I was not producing enough self lubrication during sex. However, Thursday night i was feeling the same symptions. Usually the feeling goes away after a day or so but last night I woke up crying and in a lot of pain. The area is red, and very tender and burns when I go to the bathroom. Could this be a bad case of a UTI?
