Genital warts are small, skin-colored or whitish-grey growths that appear on or around the genitals and anus. They can show up anywhere from one to six months after exposure to HPV, and many are so small or flat that you can’t see them with the naked eye. Knowing what to look for, where to check, and what else it might be can help you figure out your next step.
What Genital Warts Look Like
The classic appearance is a small, rough, raised bump that’s either skin-colored or slightly lighter than the surrounding skin. They have a bumpy, irregular surface. When several warts cluster together, they take on a cauliflower-like texture that’s easier to spot. But not all genital warts look like this. Some are completely flat, and some are so tiny you’d miss them without close inspection.
They’re usually painless. Occasionally they cause mild itching, a burning sensation, slight discomfort, or minor bleeding, but many people feel nothing at all. That’s one reason they’re easy to overlook. If you’re experiencing significant pain, the bump is more likely something else.
Where They Typically Appear
In people with a penis, warts most commonly show up on the shaft (especially in circumcised individuals), under the foreskin, or on the scrotum. In people with a vagina, they tend to cluster around the vaginal opening. For everyone, the perineum (the skin between the genitals and anus) and the skin around the anus are common sites, even without anal sex.
Warts can also develop internally, inside the vagina, on the cervix, inside the urethra, or inside the anal canal. Internal warts are harder to detect on your own because you can’t see or always feel them. If you notice warts on external skin, it’s worth getting checked for internal ones too.
Conditions That Look Similar
A lot of normal skin features in the genital area get mistaken for warts. Before you panic, consider these common look-alikes:
- Pearly penile papules: Tiny white or flesh-colored bumps that form a neat row around the head of the penis. They’re a normal variation, not an infection, and they’re evenly spaced in a way warts aren’t.
- Fordyce spots and Tyson’s glands: Small yellowish bumps made of oil glands. They appear on the shaft of the penis, the labia, or near the frenulum. They’re completely benign and extremely common.
- Skin tags: Soft, smooth, floppy bits of skin that hang from a thin stalk. They often show up in skin folds near the groin. Unlike warts, they’re smooth rather than rough or bumpy.
- Angiokeratomas: Small red or purple spots, often on the scrotum, caused by dilated blood vessels. Their color makes them distinct from warts.
The key differences are texture and pattern. Warts tend to be rough, irregularly shaped, and can cluster. Normal anatomical features are usually symmetrical, smooth, or uniform. Still, the overlap is real, and even dermatologists sometimes need a closer look to tell them apart.
How Genital Warts Are Diagnosed
There is no at-home test for genital warts. Diagnosis happens through a visual examination by a healthcare provider, and that’s usually all it takes. A trained eye can distinguish warts from normal skin variations in most cases.
For internal warts, the process involves more specialized tools. A pelvic exam, sometimes with a colposcopy (a magnifying device for the cervix and vaginal walls), can identify warts inside the vagina or on the cervix. An anoscope, a small tube-shaped device, lets a provider look inside the anal canal. In uncertain cases, a small tissue sample can be taken and examined under a microscope.
One important limitation: there is currently no approved HPV screening test for the penis, anus, vulva, or throat. The only HPV test available screens the cervix for high-risk strains. This means that for most people, visible warts or a clinical exam are the only way to know.
The Timeline From Exposure to Symptoms
Genital warts typically appear one to six months after you’re exposed to HPV. But the virus can stay dormant for much longer, sometimes years, before warts develop. This makes it nearly impossible to pinpoint exactly when or from whom you got the infection. You could have been exposed by a recent partner or one from years ago.
It’s also entirely possible to carry the HPV strains that cause warts and never develop visible ones. Your immune system may suppress the virus before it produces any growths. This is why genital warts can seem to appear “out of nowhere” in a long-term relationship, causing confusion and unnecessary suspicion.
What a Self-Check Looks Like
You can examine yourself at home using good lighting and a hand mirror. Check the full genital area, including the shaft and base of the penis or the outer labia, the perineum, and the skin around the anus. Feel for any small bumps with your fingertips. Warts often have a slightly rough or grainy texture compared to the smooth surrounding skin.
If you find something suspicious, don’t try to diagnose it yourself and don’t attempt to treat it with over-the-counter wart removers designed for hands or feet. Those products are too harsh for genital skin. A primary care provider, gynecologist, urologist, or dermatologist can give you a clear answer, usually in a single visit.
