Im 15 years old, and for the past week I have been constipated. Usually when im constipated, i get penis pains and the tip of the foreskin gets red and burns. Also, when this happens, i get a yellow-white liquid that comes out from what seems like the sides of the shaft, not from the pee hole. Also, i tried masturbating today and i noticed that when i was cleaning off the liquid that was getting pushed up, i saw some red on the tissue. Should i be concerned or will this heal on its own?
