I have noticed, in the past few days, a pain in the underside of my penis, right near the scrotum, but, most definitely, the penis. It is a pain that is constant, though, by no means, unbearable. It is made more pronounced when I stand and cough - i.e. tense it. Whenever I get an erection, it hurts more, too. I am having no problems urinating, though I do notice that it is passing less 'seamlessly' than before - i.e. not passing always in a straight line, and coming out, to put it bluntly, kind of like a sprinkler.
There is also a pain on the bottom of my scrotum, kind of between my anus and my scrotum. It is on the right-hand side of the area. That hurts when I stand up, but is not constant. The penis pain, on the under-side of it, is the most concerning.
I am only 17, 6 foot 2. Pretty healthy. Never had sex. I fear it may be due to masturbation, given that the pain started after I masturbated for the first time in a few days.
Any advice would be most useful.
