Sexually Transmitted Diseases/White spots/bumps on glans



Hi Doc,

About two months ago someone performed oral sex on me without a condom. A few days later I noticed some whitish spots on my penis glans but didn't pay much attention to it.

Attached are two pictures I took yesterday. They are noticeable when I've had the foreskin over the glans for a few hours and the glans is not dry. They're almost invisible whenever the foreskin is retracted and the glans is dry...

Any ideas what it could be? I'm going a little bit insane with it to be honest.

Thanks so much.

Hello Ted,
The whitish areas appear to be little islands of skin. Imagine the glans being coated with a thin layer of unkeratinized epithelium, that gets partially worn off during the friction associated with sex; oral sex combines some mild digestive enzymes to further remove some of that skin.  But a few areas persist, and that is what you are seeing.  My guess is that if you were to wait a week or two, everything will return to normal appearance.  

If you try to use vinegar or otherwise vigorously wash the glans, those little islands may become dislodged, but then the head will feel more sensitive until the protective layers are restored.  

Good luck!

Almost any question or concern about gay men's health issues, sexually transmitted infections, abnormal Pap smears, anal cytology (anal "Pap smears"), etc. There is no such thing as “d/d free” or “clean” (free of infection), so why do so many of us deceive ourselves into thinking that some people are indeed totally free from a potentially infectious disease, like HIV, herpes, hepatitis, syphilis, chlamydia, warts, gonorrhea, etc., just because they say so? Clinical laboratory tests are not perfect, and having a “negative” or “nonreactive” test does not mean that a person is free from infection. Perhaps at the moment the test was taken, the person was uninfected; or, perhaps, the test wasn’t sensitive enough to detect presence of the infection. There is really no way that anyone can determine that they are truly “disease free,” and there are over a hundred of infectious conditions that can be spread without your knowing anything. Rather than trying to “pre-screen” or “serosort” a potential sex-mate with deceptive questions that are impossible to know by today’s technologies, a wiser option may be to consider everyone infected with something, and either use appropriate protective measures (“safer sex”), or accept the responsibility and consequences of possibly “catching” something from someone who’s hotter than expected (pun intended!). There is much research that supports the contention that an HIV positive person reliably taking HIV medications, and having an undetectable viral load, presents a lower risk for transmission of HIV than people who may think or say they are HIV negative, but are not. Food for thought!
