Hi, I would like to ask, a couple of days ago in the morning I went to take a shower, and I noticed some yellowish small stains on my underwear, I was confused since I have never seen anything like that, after that I changed my underwear, but the following morning I again got the stains on my underwear. During that day I had been feeling a bit of tingling sensation at the tip of my penis sometimes, but not burning. So im guessing it’s a discharge of some substance. I have no other symptoms or issues. But I ALWAYS use protection, so I don’t know how could I get it. Please any help!
