Sexually Transmitted Diseases/Spot of Discoloration on Penile Shaft


Country - US

Hello, 2 months ago I noticed this small patch on penis. At first it would get dry like fungas, and also silvery. I would put water on it and that would solve it. That eventually went away about a month ago and it has since not changed a bit other then a normal colored streak running through the middle, and maybe a bit lighter. I am sexually active, but always protected sex with a condom. I do have bad fungus on my feet, and the circular spot did look like that at first, but now has since faded and is just a spot. I also have eczema, but this spot does not react to the same cream I use for eczema. Any idea what this is? Thanks

ANSWER: Hi Stephen,
Looks fine to me. The photo does not show any obvious pigmentary changes in the skin. Since you do have a foot fungus (tinea pedis), it is possible to also have a fungus elsewhere, such as on your penis or other areas of the skin. The cream used for eczema can cause skin fungal infections to worsen, so I would avoid using unless certain that your rash is really eczema.

Good luck!

---------- FOLLOW-UP ----------

QUESTION: Alright, Thank you! I guess the follow up question would be, since this is not an STD, does this discoloration look to be like some sort of fungas? I am going to the doctors in a few days, but I do have a tendency to get mad anxiety over things such as this and just want to have some peace of mind :P

Thanks once again!

Hello Again, Stephen,
The photo is not explicit enough to say one way or another whether it is a fungus. Although there are many types of skin fungi, many skin fungal infections usually appear with a pale central area, and a redder more elevated periphery. In order to know for sure, you need to stretch the skin tight, and have examined under a bright light and magnification.  As I said previously, this is NOTHING to freak about!

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!
