Hi just wanna ask i have some white stains on my underwear after i got a mild erection.However, after 1 hour, the same stain appear again on my new set of underwear. They dry up and feels crusty on my underwear.  I wonder if they are just pre-cum or infection. The last time i am sexually active is 3 months back and I was clear by local medical doctor for STI ( they say i got NGU and I was cleared by them during that time).
Hello appreciate your concernLooking at your description this could be related to infection leading to urethral discharge or may be pre-cum when you get sexually excited with pornography. In my opinion you should go for certain investigations like blood for hemoglobin CBC or liver function test and urine culture and sensitivity testy may require a course of antibiotics under supervision of your doctorMeanwhile maintain good hygieneHave healthy and nutritious foodAvoid smoking and Chat Doctor.
