hi i am 23 i was having nocturnal emission since 4 years at an average of 5 times a week. i recently went to oa doctor when this got more annoying.he has given me depsonil 25 at bedtime n some anti biotics. night discharged has stopped but now since two days i am noticing white thick sticky substance that i pass with urine.. it looks like dead sperms or something it sticks to the pot n doesnt go off even after flushing it twice..i touched it it very thick n white. it pains after it comes out, i can feel it moving out through the penis involuntarily it gives me burning sensation n causes pain post urination. also when i urinate n come out of the rest roon after 2 or 5 mins i involuntarily pass urine.. i have a back pain n feel vomiting also.. i earlier used to have lot of abdominal pains. for which i did a CECT abdn with oral contrast that was normal. my usg is normal too.. i dont have any other medical condition
i have lost all sexual urge also and my penis has become small.. i have stopped masterbating since 3 years
what could be it ?

first week
one Azithromycin 250 mg twice a day ( morning n evening)
one depsonil 25 mg bed time

for this week my discharge completely stopped and i was normal

second week
one depsonil 25 mg bed time + one neuro aid 15000mcg bed time
one dilotin mps twice a day (morning n evening)
