Genital warts are small, flesh-colored bumps with a rough, folded surface, typically just a few millimeters across. They’re caused by certain strains of human papillomavirus (HPV), and they can appear anywhere from one to six months after exposure, making it hard to pinpoint exactly when you picked up the virus. Here’s how to recognize them and what to expect if you think you might have them.
What Genital Warts Look Like
The classic genital wart is a flesh-colored papule with an irregular, folded surface. Many people describe them as looking like tiny cauliflower florets. They start small, often just a few millimeters in diameter, but individual warts can merge together into larger raised patches (called plaques) that span several centimeters. Sometimes they appear in a line if the virus entered through a scratch or small tear in the skin.
Not all genital warts look the same. Some are flat and smooth rather than raised and bumpy. They can be skin-colored, slightly pink, or occasionally darker than the surrounding skin. You might notice a single bump or a cluster of several. Because of this variation, it’s easy to confuse them with other skin conditions like skin tags, fordyce spots (harmless oil gland bumps), or molluscum contagiosum.
Where They Appear
In women, genital warts commonly show up on the vulva, the walls of the vagina, the perineum (the area between the genitals and the anus), the anal canal, and the cervix. In men, they tend to appear on the tip or shaft of the penis, the scrotum, and around or inside the anus. Warts can also develop in the mouth or throat after oral sex with someone carrying the virus, though this is less common.
Warts that grow internally, such as inside the vaginal canal, on the cervix, or within the anal canal, are harder to spot on your own. You may not know they’re there unless a healthcare provider finds them during an exam. Cervical warts in particular produce no obvious external symptoms and are typically discovered during a pelvic exam or Pap screening.
What They Feel Like
Most genital warts don’t hurt. The majority of people notice them because of how they look or feel to the touch rather than because of pain. That said, warts in certain locations can cause itching, mild tenderness, or irritation, especially if they’re in areas that experience friction during sex or from clothing. Larger clusters may occasionally bleed during intercourse. Some people with genital warts report no physical sensations at all and only discover them by chance during a shower or self-exam.
How Long They Take to Appear
After you’re exposed to HPV, warts typically show up within one to six months. But the timeline isn’t always that straightforward. Some people carry HPV for months or even years before warts become visible, and many people with HPV never develop warts at all. This long, unpredictable incubation period is one reason genital warts can feel like they appeared out of nowhere, even in a long-term relationship. It doesn’t necessarily mean a recent partner gave you the virus.
The HPV Strains Behind Genital Warts
More than 90% of genital wart cases are caused by HPV types 6 and 11. These are classified as “low-risk” strains, meaning they cause warts but are not associated with cancer. This is an important distinction: the HPV strains responsible for cervical, anal, and throat cancers (primarily types 16 and 18) are different from the ones that cause visible warts. Having genital warts does not mean you have a cancer-causing strain, though it is possible to carry more than one type of HPV at the same time.
How Doctors Confirm the Diagnosis
Genital warts are almost always diagnosed by visual inspection alone. A doctor or nurse examines the bumps, considers their appearance and location, and can usually make a confident diagnosis without any lab work. HPV testing is not recommended for diagnosing genital warts because test results don’t confirm whether a specific bump is a wart and don’t change how it would be treated.
A biopsy, where a small tissue sample is taken and examined under a microscope, is reserved for specific situations. Your provider may recommend one if the bump looks unusual: if it’s darkly pigmented, feels hard or fixed to deeper tissue, bleeds, or has an ulcerated surface. Biopsy is also considered when a diagnosis is unclear, when warts don’t respond to treatment, or when a person has a weakened immune system (including HIV), because certain skin cancers can sometimes resemble or develop within genital warts.
What You Can Check at Home
You can do a visual self-exam in good lighting using a handheld mirror. Look for small, raised bumps with a rough or textured surface on the external genital area, the perineum, and around the anus. Run your fingers gently over the skin; warts often feel slightly rough compared to the surrounding tissue. Check both sides of the labia or the full shaft of the penis, including the underside.
Keep in mind that a self-exam has real limits. You can’t see internal warts, and many skin-colored bumps in the genital area are completely normal anatomy. Pearly penile papules (small, smooth bumps around the head of the penis) and vestibular papillae (tiny projections at the vaginal opening) are harmless and frequently mistaken for warts. If you’ve found something that worries you, a visual exam by a healthcare provider is the fastest and most reliable way to get a clear answer. The visit itself is quick, and in most cases, no blood draw, swab, or biopsy is needed.
