I'm not a man - so bear with me here. From what you are describing (in my 2nd hand experience) it could be a yeast infection. Many people wrongly think that only women get yeast, but men in fact do as well & sorry to say it seems from what I've seen, mostly men with in-tact foreskin. I know you don't want to hear go to the Dr - but really you should. If in fact it is a yeast infection as it sounds to be, they can prescribe you a single dose of an antifungal pill & that will get rid of it. Yeast infections are passed between partners, so if you had a partner w/ yeast, you probably caught it, it's not an STD, it's an infection. NEVER leave anything that seems abnormal untreated on your genitals, you don't want to risk any loss of function sexually or reproductively. It's better to be safe than sorry.
