I'm 22. For The Last Couple Of Days I've Been

I'm 22. For the last couple of days I've been getting some pain in my lower abdomen, usually on the sides, both right and left, and maybe a little pain in the back. Then today my penis has become sensitive to the touch. Urination and everything else is fine. No burning, no discoloration, nothing unusual. I'm an athlete and work out in the gym. My clothes do not bother my penis but I feel pain if I touch it with my finger. Can you help me?
