This question is super embarrassing. So I went pee about 20 minutes ago and there was no blood in the pee. Then about ten minutes ago, I masturbated (I masturbated harder than I usually do). Anyways, In the process of the masturbation, I noticed a little droplet of blood on my penis hole. It wasn t really deep red, it looked watered down a bit. Do you think this blood was from me masturbating too hard? Should I be concerned and see my doctor, or should I just let it be? I ve never participated in any sexual activities. Also, yesterday I also woke up with intense kidney pains. I m not sure if this would have anything to do with it. And thank you so much for the answer. I appreciate it so much. I m sorry about my embarrassing question.
