Penis discharge no pains, bleeding, different colors , swollen testicals none of that, but today i seen that there was like a white creamy thick substance in my underwear and i immediately looked it up and now im asking you guys what do you think ?

See below : Discharge from the penis is not a "normal" occurrence in men. Recommend prompt medical infection to determine cause and rule out infection/STD. The most common causes of penile discharge are chlamydia, gonorrhea, ureaplasma, mycoplasma and trichomoniasis. Most common benign cause of discharge would be either a nocturnal emission or an overflow/leakage of normal prostate fluid (aka prostatorrhea).
