Hello, I am an 18 year old male in college.
As of these past few days, I have been sick with a stomach virus that had been spreading on my campus. I came down with the virus on Tuesday and was vomiting profusely for hours and only just started feeling better this morning, minus a few aches. The symptoms I had from the stomach virus were vomiting, inability to keep down liquid or food, aches, and a fever.
Now my real question is, this morning I discovered that my semen was abnormally yellow. I found this incredibly strange and alarming, as my semen is usually fairly clear. The only natural attribution I could think of as to why my ejaculate would be yellow in tint would be because I have been masturbating much more frequently since I have been sick (I'm still a teenager after all), or that my illness over the past few days had in some way caused the discoloration.
I'm becoming more and more worried that this could be Chlamydia, Gonorrhea, or Urethritis. I would rather be assured that it likely isn't, but would prefer a more professional opinion. It isn't exactly easy to get tested when you're a first year without a car to drive to the clinic...
