Sexually Transmitted Diseases/expanding rash on inner thighs, scrotum


Hi, I first want to thank you for your dedication to this site, it shows a lot.

My name is Clayton, I am an 18 year old coloured male from Cape Town, South Africa. In June of this year I developed a rash spanning from the sides of my scrotum to my lower pelvis and inner thighs. It has developed a darker colour (I am non-white) than the rest of my skin, and starts itching often.

I have a bad habit of scratching open the skin as it is very weak. Initially I thought it would pass, now it grows bigger and will not heal. I am a very clean guy and make sure that my genitals stay that way. My penis itself is not affected in any way.

I do have medical aid, but am too embarrassed to visit my dermatologist until I get an idea of whether or not I should be worried. I don't have any sexual confidence and have stopped showering at gym.

Please help me, I'm really scared. Thank you so much.

Hello Clayton,
A photograph sometimes helps with skin diagnoses! But your description sounds very much like a skin fungal infection. I don't know what type of skin antifungal medications are available without a prescription at your local pharmacy, but I would check in the athlete's foot section and search for a cream with one of these active ingredients:  terbinefine, tolnaftate, miconazole. Apply according to the instructions for at least a week or two, to all skin areas affected by your rash, regardless of the itching.

Good luck! Hope it goes away soon!

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!
