Dear Alice,

I took a piss and found a purple mark on my penis. I have taken a blood test, and the results are on the way to check for HIV, but I can't wait. What do you think it is? Did I just masturbate too hard? I did just yesterday.

Dear Blue is my favorite color, not purple,

Bruises and bumps are no fun, especially when they appear somewhere sensitive, like a penis. It's certainly possible that the purple mark you've noticed is a bruise, although bruising is not typically a symptom of HIV. Bruises develop when the small blood vessels under the skin get broken — what may have happened if you "masturbated too hard." A bruise will usually go away on its own within a few weeks. Another possibility is that blood pooled underneath the skin after an injury, causing a hematoma. Unlike with a regular bruise, the skin may feel lumpy or spongy. Like bruises, though, hematomas are not usually a cause for concern.

A purple mark on the skin might also be a blood spot. Blood spots may either be small, flat, red or purple spots or look more like a bruise. They are not caused by an injury. Sudden, unexplained, and/or more frequent blood spots or bruising may be due to inflammation of the blood vessels, some nutritional deficiencies, a bleeding or clotting disorder, or certain medications. You should see your health care provider if you notice that

  • the mark doesn't go away within a few weeks;
  • you notice other bruises or blood spots where you haven't been hurt;
  • you get large bruises after minor injuries;
  • you have bleeding from the gums, nose, or intestinal tract (blood in the stool); or
  • you are experiencing any pain,

as these can be signs of a more serious problem.

It sounds like your concerned about HIV. Do you think you've been exposed to the bodily fluids (sexual fluids or blood) of a person with HIV? HIV is commonly transmitted through having unprotected sex or sharing needles with an infected person — neither of which would necessarily lead to bruising or purple marks on a penis — but if you've had either type of exposure, you've taken a great first step by getting tested. If you are a Columbia student, you can log in to Open Communicator or call x4-2284 to make an appointment with Primary Care Medical Services. Columbia students can also go to GHAP during walk-in hours for confidential HIV testing and counseling. Since you've already had an HIV test, you can ask your health care provider about other possible causes of the spot in question when you go to get your test results. Take care,

Alice

Yeah bruises and spots happen after rough sex/masturbation. Take care of your penis you only get one.

OMG this was such helpful advice!!!!! I have recently been having unprotected sex with several women and one morning when going for a piss I also noticed a purple round mark on my penis. First thing I did was panic like mad, I did not know what the hell to do. I was going to go A&E I was in such a panic. However I decided to google what could cause it as I'm sure most people do when they find something there not sure about. When reading this comment my mind was put to rest however I am still going to take a HIV blood test as from now always use protection. Thanks a lot Alice.
