Burning & bleeding during urination : UTI or sex ?

Burning feeling during urination or "disuria" is typical for inflammation of the distal parts of urinary tract such as the urethra and bladder. Frequent urination is also present during these conditions. Blood in the urine (hematouria) can be also present in cases of bladder inflammation (cystitis) although not so often. Inflammation of the urinary tract is usually due to infection. Urinary infections are more common for women than men. It is hard to believe that sex caused urinary infection because you used a condom. Anyway, you can visit a gynecologist for a check up, to report your symptoms, and to diagnose the condition.
