Right, so I recently had a case of epididymitis and was on two months of doxycycline, and am now on sulfameth. I hadn't masturbated in roughly a month, aside from having a nocturnal emission 2 weeks ago. I did earlier today, and there was a pain between my scrotum and my anus as I ejaculated. I know that I had an infection from some source (dirty underwear is my assumed culprit given that I'm a virgin), but don't know if this fact combined with that pain is alone enough to think prostatitis plausible. I've no other known symptoms. Perhaps understandably, I'm a tad paranoid on this issue, mainly insofar as it may affect fertility (though I'm just in my late teens now, I do very much want kids one day).
