It sounds like you caused an abrasion and got an infection going. You may need to get your urine checked to see if you have a urinary tract infection. Once that is cleared up, remember to use good hygiene and lube so you don't injure things. I personally don't feel it is useful to feel guilty about this type of exercise as long as it doesn't replace your interest in real sex. I think porn can be a problem because it is too hard core and it may dull your interest in real sex.
Hi kyle, well the best thing for you to do now, is take a 4 week break, this should help reboot your system, so thats no masturbating, no sex and no sexual games, and the last one is thtis if your watching porn as an add to your masturbating the double it to 8 weeks, it your only wayout of your problem, and if porn is your downfall the now is the time to wipe the slate clean and give it up, just remember what is done by the hand is remembered by the brain.
Good Luck
