Genital warts typically appear as small, flesh-colored bumps on or around the genitals or anus. Individual warts usually measure 1 to 2 millimeters in diameter, much smaller than a pencil eraser, though clusters can grow considerably larger. They can be so small and flat that you can’t see them at all, or they can group together into a distinctive cauliflower-like shape.
Color, Texture, and Shape
Genital warts don’t always look the same from person to person. They can be flesh-colored or a close variation of your skin tone, but they also show up as pearly, dark purple, brown, or gray. The surface feels bumpy or rough to the touch, which is one of the more reliable ways to distinguish them from other skin growths.
In terms of shape, they fall into a few categories: flat growths that sit close to the skin’s surface, raised papules, or pedunculated warts that extend outward on a narrow base. A single bump is common early on, but warts frequently grow in small clusters. When several cluster together, they create that cauliflower appearance that’s often described as the hallmark look. Over 90% of genital wart cases are caused by two specific strains of HPV (types 6 and 11), and these strains tend to produce this characteristic shape.
Where They Appear
In women, warts usually occur in or around the vagina, on the cervix, or around the anus. In men, they commonly appear on the tip of the penis, around the anus, or on the scrotum, thigh, or groin. Warts can also develop internally, inside the vaginal canal, the urethra, or the anal canal, where they aren’t visible without a medical exam.
If you have external warts near the vaginal or anal opening, there’s a chance warts have also developed inside. Internal warts sometimes cause bleeding, discharge, or irritation that prompts further investigation with a speculum exam or proctoscopy.
How They Develop Over Time
Genital warts don’t appear on a predictable schedule. Some people develop them within weeks of sexual contact with someone carrying HPV, but it’s far more common for warts to take months or even years to show up. This long incubation period makes it difficult to pinpoint when exposure happened.
Most warts start as tiny, soft growths that are easy to miss entirely. Over time, they can cluster together, grow larger, or take on a stalk-like appearance. Not all warts progress this way. Some stay small and isolated, and in many cases the immune system eventually clears the virus on its own.
Genital Warts vs. Skin Tags
Skin tags and genital warts can look similar at first glance since both are small, flesh-colored growths. The key differences come down to texture and structure. Skin tags are soft and pliable. They grow on thin stalks off the skin’s surface, and when you press them, they bend easily. Genital warts, by contrast, feel bumpy or rough and sit flatter against the skin. They’re firmer to the touch and more likely to appear in clusters.
Genital Warts vs. Pearly Penile Papules
Pearly penile papules are a normal anatomical variation, not an infection. They appear as small, dome-shaped bumps arranged in neat, symmetrical rows around the head of the penis. That orderly pattern is the biggest visual clue. Genital warts vary in shape and size and can appear anywhere on the shaft, scrotum, or surrounding skin, not just in tidy rows around the glans. If the bumps are uniform, evenly spaced, and confined to the ridge of the penile head, they’re almost certainly papules rather than warts.
Genital Warts vs. Vestibular Papillomatosis
In women, a similar case of mistaken identity involves vestibular papillomatosis, a normal variant of vulvar anatomy. These are small, shiny, pink, soft papules that appear on the inner labia and the vestibule (the area just inside the labia minora). They’re smooth on the surface and are not caused by HPV, despite looking superficially similar to warts. Vestibular papillomatosis papules tend to be symmetrical and evenly distributed, while genital warts are more irregular in shape and placement. Under magnification, the two have different surface patterns, which is why a dermatoscope exam can settle the question quickly.
What They Feel Like
Genital warts are often painless. Many people discover them only by touch or during a routine exam. In some cases, warts cause itching or mild irritation, particularly if they’re in an area subject to friction. Large clusters or warts in sensitive locations like the urethral opening or anal canal are more likely to cause discomfort, bleeding, or a feeling of fullness. But the absence of pain doesn’t rule them out. The majority of genital warts cause no symptoms beyond the visible or tactile bump itself.
When Warts Aren’t Visible at All
Some genital warts are completely flat and flush with the surrounding skin, making them invisible to the naked eye. A healthcare provider can sometimes detect these by applying a mild vinegar solution to the skin, which causes affected areas to turn white temporarily. For internal warts on the cervix, routine Pap smears or HPV tests may pick up signs of the virus even when no warts are visible externally. Visual inspection with good lighting is usually enough to diagnose typical warts, but smaller or flatter lesions sometimes require magnification with a dermatoscope.
