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 I’m 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). .
