About a week ago my boyfriend and I had sex. Since then I have felt a huge amount of discomfort in my genital area and a few days ago started to feel a burning sensation when I urinate. People have suggested that it may be a yeast infection or UTI but there are no other symptoms; discharge, itching, etc. I don't know if I possibly tore something or if it is just a burn caused by the friction of our bodies. My boyfriend told me that he even noticed a mark on his penis that resembled a rug burn. I've tried drinking a lot of water in hopes that it would change the pH of my urine because the pain is so extreme that I have been on the verge of tears. The weird thing is, the other night I had a couple of beers but not enough to be drunk or to even be buzzed for that matter but after doing that, the general discomfort was still there but it no longer burned when I went to the bathroom. I don't even know if that had anything to do with it or not but that's the second time it had happened. We've both been checked for STDs and are clear of any so it's hard for me to believe that this could be something like that. Has this ever happened to anyone else??
