Genital Warts vs Skin Tags: How to Tell the Difference
Found a new lump down there and now you’re staring at your phone? Let’s be real, it’s a horrible moment. The short version: skin tags are harmless flaps of skin that aren’t contagious. Genital warts are caused by a virus (HPV) that spreads through sexual contact. They can look alike, and you can’t reliably tell them apart by eye alone. This guide shows you what usually separates them, what to do next, and when a clinic visit is the right call.
TL;DR
- Skin tags are usually soft, smooth and hang from a little stalk. Genital warts are more often rough, bumpy or flat, and tend to appear in clusters.
- Skin tags aren’t contagious and aren’t a sign of an STI. Genital warts are caused by HPV, which spreads through skin-to-skin contact, even when no warts are visible.
- Don’t use pharmacy wart treatments or cut anything off yourself. Both conditions are best confirmed and treated by a clinician.
- A new genital lump that you can’t identify deserves a sexual health clinic check, especially if it bleeds, itches, hurts or looks different from the skin around it.

Why these two get mixed up
Both show up as small, skin-coloured bumps in the same places: around the vagina or vulva, the penis, the anus, the groin and the inner thighs. Both are usually painless. Both can sit there quietly for months.
The difference is what’s behind them. One is a bit of excess skin, often from friction. The other is an infection. That’s why the question matters, and why it’s worth getting a proper answer rather than guessing.
What genital warts look and feel like
The NHS describes genital warts as small lumps, usually rough, around the vagina, penis or anus. You might have one or a cluster, sometimes in a cauliflower-like group. They can be soft or firm, and white, red, skin-coloured or darker than the skin around them.
The 2024 BASHH guideline on anogenital warts adds some detail. These are usually benign lesions up to 5 mm, most often multiple and non-pigmented. They come in several forms: soft and finger-like (papillomatous), hardened (keratotic), flat or small and domed (papular).
In plain words, warts tend to:
- feel rough, bumpy or slightly grainy
- sit flatter against the skin, or look like tiny cauliflower florets
- appear in groups that grow or multiply over weeks
- show up in more than one spot
Most of the time they cause no symptoms at all. The NHS notes they can sometimes cause pain, itching or bleeding, discomfort during sex, or changes to urine flow if they’re near the urethra.
What genital skin tags look and feel like
Cleveland Clinic describes genital skin tags as soft, smooth, loose and movable growths attached by a fleshy stalk. They’re usually skin-coloured or slightly lighter or darker, and commonly 1 to 5 mm across.
The tell-tale features:
- smooth, soft surface
- hangs off the skin on a thin stalk, a bit like a tiny teardrop
- you can gently move it without it feeling fixed in place
- tends to stay the same shape and size for a long time
- often appears where skin rubs, such as folds, the groin or the inner thighs
The same source gives a handy rule of thumb: skin tags are raised, smooth and generally separate from each other, whereas genital warts may lie flatter, feel rough or bumpy, and cluster.
Side by side: genital warts vs skin tags
| Genital warts | Skin tags | |
|---|---|---|
| Surface | Rough, bumpy, sometimes cauliflower-like | Smooth and soft |
| Shape | Flat, domed or finger-like, broad base | Hangs from a narrow stalk |
| Colour | White, red, skin-coloured or darker | Skin-coloured, slightly lighter or darker |
| Number | Often several, in clusters | Often single or a few, usually separate |
| Cause | HPV infection | Friction and skin-related factors |
| Contagious | Yes, through skin-to-skin contact | No |
| Sign of an STI | Yes, it is an STI | No |
| Usually painless | Usually, but may itch, bleed or hurt | Usually, unless rubbed or caught |
Treat this table as a guide, not a diagnosis. Plenty of real-life lumps sit in the grey area between the two columns.
What causes each one
Genital warts: HPV
Genital warts are caused by the human papillomavirus. BASHH says most cases come from HPV types 6 and 11: around 90% of anogenital warts are attributable to these two types.
The NHS explains that the virus spreads through skin-to-skin contact. That includes vaginal or anal sex, shared sex toys and, rarely, oral sex. You can pass it on or pick it up even when no warts are visible.
BASHH also notes that sexual transmission is the usual route, and that there is no good evidence for spread through inanimate objects. The warts themselves are benign, although other HPV-related lesions that carry cancer risk can sit alongside them, which is one reason a proper examination matters.
A wart showing up doesn’t tell you who gave you the virus, or when. HPV is very common and can stay dormant, so a first wart may follow contact from months or years earlier. No need to play detective or point fingers.
Skin tags: friction and body factors
Cleveland Clinic says skin tags aren’t contagious and aren’t a sign of an STI. Friction in skin folds and against clothing may contribute. Factors associated with them include pregnancy, insulin resistance or type 2 diabetes, higher body weight and genetics.
So a skin tag says nothing about your sexual history or your hygiene. They’re simply common.
Other lumps that can fool you
It isn’t always a straight two-horse race. Early genital warts can resemble molluscum contagiosum (small, firm, dome-shaped bumps with a dimple), Fordyce spots (tiny pale or yellowish dots that are a normal variation of oil glands) and other benign bumps. Ingrown hairs and cysts can also look suspicious at first glance.
Blisters and painful sores are a different story. They point more towards herpes than warts or skin tags. If you want to understand how herpes is treated and when to see a doctor, this guide to cold sore treatment and when to see a doctor explains the recurrence pattern and the signs that mean you shouldn’t wait.
The point is the same each time: if you can’t confidently name it, get it looked at.
Can genital warts or skin tags affect your health or fertility?
Skin tags are harmless. They only cause trouble if they get caught on clothing, rub or bleed, or if they bother you.
Genital warts usually don’t cause symptoms either, but the NHS lists possible pain, itching or bleeding, discomfort during sex, and changed urine flow. The research we reviewed doesn’t tie either condition to reduced fertility, so there’s no need to assume the worst. If you’re trying for a baby and have a new genital growth, mention it to your clinician so they can check it properly as part of the wider picture.
How a clinician tells them apart
Sexual health clinicians do this all day, and most lumps are identified by a simple visual examination. BASHH recommends careful examination of the external anogenital area and the urethral opening. If the diagnosis is uncertain, or treatment isn’t working, a biopsy (a tiny sample sent to the lab) should be considered. An urgent biopsy is recommended for atypical features or suspected cancer.
NHS Borders guidance lists the features that raise concern and call for senior sexual health review: large or solitary lesions, pain, itching, bleeding or a colour difference. It’s rare, but it’s the reason “just wait and see” isn’t great advice for a lump that’s changing.
When to get it checked
The NHS advises going to a sexual health clinic if you have:
- a painless lump or growth around the vagina, penis or anus
- itching or bleeding around the genitals or anus
- a change in how you pee that doesn’t go away
- a partner who has been diagnosed with genital warts
Add to that any lump that is growing, bleeding, painful, unusually coloured or different from its neighbours. You can search for a clinic via the NHS, and sexual health services in the UK are free and confidential, with no need to see your GP first.
Booking in can feel awkward. It really isn’t for the person on the other side of the desk. They’ve seen it all, and a five-minute look usually ends weeks of worry.
Treatment: what’s safe and what isn’t
Genital warts
According to the NHS, genital warts can clear on their own, sometimes within six months, or be treated with a prescribed cream, liquid or ointment, cryotherapy (freezing) or surgery. Treatment can take weeks or months, and warts may come back.
BASHH adds a useful bit of perspective: treatment aims to clear visible warts and improve appearance. Delaying treatment is acceptable because lesions may regress by themselves. There’s no evidence that treating warts reduces onward transmission.
One firm rule from the NHS: don’t use pharmacy wart treatments on genital warts. Products made for verrucas and hand warts aren’t meant for this delicate skin.
Skin tags
Cleveland Clinic’s advice is to have a healthcare provider confirm the growth and remove it professionally if needed. Don’t snip, tie off or burn it yourself, and avoid over-the-counter removal products. Both can lead to infection, bleeding or skin damage. A provider can remove a genital skin tag if it makes you self-conscious or affects your sex life. If it doesn’t bother you, it’s fine to leave it alone.
Where an at-home test fits in
Here’s the honest bit. A lump needs eyes on it. No kit can tell you whether a particular bump is a wart or a skin tag, and we’d never suggest swapping an examination for a test when you have a growth that’s changing, bleeding or painful.
What a test can do is help with the bigger question: could this be HPV, and what else should I rule out? If you’ve had a new partner, a partner with warts, or you simply want to know where you stand, our HPV rapid test kit gives you a private first step at home, with results in around 15 minutes. If it’s positive, or you have any lump at all, the next step is still a clinic.
People who notice one change often want to check for other infections too. Some of those, like gonorrhoea, don’t always show obvious signs, which is covered in our guide to early gonorrhoea symptoms in men and women.
Our view: peace of mind without the waiting room
We built Rapidtest for the person who is busy, a bit anxious and would rather not sit in a waiting room to ask a question they’re already embarrassed about. Our kits are CE-certified, arrive in discreet packaging, come with full instructions and give results in around 15 minutes, with no lab return.
But we also believe in being straight with you. Home testing is a screening tool, not a substitute for being examined. If you have a lump you can’t identify, use a test for the infection side of the story and see a clinician for the lump itself. Do both and you’ve covered every base.
The most common thing we hear is “I put it off for weeks.” The worry usually costs more than the answer does. Most genital bumps turn out to be harmless or very treatable. Finding out early just means you’re in control rather than guessing.

Check in privately, from home
If you’re unsure about your sexual health and want a discreet first step, our at-home STI and STD rapid test kits start from £21.95. They come with free UK shipping, customer support and a 60-day refund guarantee if the kit doesn’t work. Browse the full range of at-home test kits and pick what fits your situation.
Remember: a kit helps you screen, but any growth that is changing, painful or bleeding should be seen by a clinician.
What to do right now
- Don’t squeeze, scratch or cut it. Irritation makes everything harder to assess.
- Look, but don’t over-analyse. Note the size, colour, number of bumps and whether anything has changed. A quick photo for your own records can help a clinician see how it’s progressing.
- Skip the pharmacy wart paints. They’re not for genital skin.
- Book a sexual health clinic appointment if you can’t clearly identify it, or if it itches, bleeds, hurts or is growing.
- Tell recent partners if you’re diagnosed with warts, so they can get checked. It’s an awkward chat, but a kind one.
- Think about wider screening if you’ve had a new partner or unprotected sex, since you can have more than one infection without symptoms.
FAQ
Can a genital skin tag turn into a wart?
No. They’re different things with different causes: a skin tag is excess skin, while a wart is a viral infection. A lump that seems to change from smooth to rough, or that spreads into a cluster, may have been a wart all along, so get it checked.
Are genital skin tags an STI?
No. Cleveland Clinic states that skin tags aren’t contagious and aren’t a sign of an STI. You can’t pass one to a partner, and having one says nothing about your sexual history.
Can I get rid of genital warts at home?
Not with shop-bought wart treatments. The NHS says not to use pharmacy wart treatments on genital warts. A clinic can prescribe a cream, liquid or ointment, or offer freezing or surgery, and some warts clear on their own within about six months.
How do I know if my lump needs urgent attention?
See a sexual health clinic promptly if the lump is large, single, painful, itchy, bleeding or a different colour from the surrounding skin. NHS guidance treats these as features that need senior review and sometimes a biopsy. Most lumps aren’t serious, but these are the ones not to leave.
Can I have genital warts without seeing any?
Yes. The NHS says HPV can be passed on even when there are no visible warts. That’s why partners of someone with warts are advised to get checked.
