ok last time i had sex without condom was 3 weeks ago. with a condom about a week and half ago, but was in her without one for only 30 seconds. over weekend i was snowboarding did a jump and landed about 8 feet in air on my back/tailbone on right side where kidney is i think. after superbowl on monday i started feeling sick and had some diarrhea but i think it was from combination of lack of sleep and alcohol from weekend. was peeing fine for all of monday and then tuesday night i had slight burning when i urinated but only at the tip. same thing happened this morning. i have a steady flow of urine and plenty of it. any clues?
