Background Info: I'm 17 years old. I am a regular gym-goer, and a varsity football and varsity basketball player so I am pretty dang healthy. My diet is alright, but nothing to write home about. I'm a virgin, but have received oral sex and participated in other non-intercourse sexual actions. Keep in mind however, the last time I was given oral sex was months ago.
So about a week ago, I was online and I came across the term "jelqing", which I now realize is one of the dumbest things ever. If you don't know what it is, it's "natural" penis enhancement exercise. So I tried this for about 10 minutes. Shortly there after, I masturbated, and ejaculated. After masturbation, I felt the pain in the tip of my penis after I went to the bathroom. Now, this pain I had felt about 5-6 times before sporadically over the last 3-4 years when I masturbated. So I figured it was just the same thing as it was before. It usually was over by morning. The next morning came, and it was still there. So I figured, "Alright, its not that bad, I can handle for another day." The next morning came, and nothing changed. That's when I began researching.
The first couple days is was a sharp pain, and urinating didn't realize change it. Now, its more of a tingling, tip of the penis, "I need to use the restroom" feeling. My bladder doesn't feel full, but my penis does. It's not painful anymore either, just very very annoying.
So my question is, could I have injured myself during PE, or is it coincidental that this happened right after?
