Common Harmless Causes of Genital Bumps
Folliculitis (Infected Hair Follicles)
Red, pimple-like bumps at the base of hair follicles. Often caused by shaving, friction, or sweating. May have a white or yellow center with pus. Usually resolves on its own in a few days with good hygiene.
Ingrown Hairs
Hairs that curl back into the skin, causing red, sometimes painful bumps. Common after shaving or waxing. You may see the trapped hair beneath the skin surface. Avoid picking—let it work its way out naturally.
Sebaceous Cysts
Round, firm lumps under the skin caused by blocked oil glands. Usually painless and slow-growing. Can occur anywhere on the body including genitals. Only need treatment if infected or bothersome.
Fordyce Spots
Tiny (1-2mm), pale yellow or white bumps—visible oil glands. Completely normal and present in most adults. Found on the shaft of the penis, labia, and around the mouth. No treatment needed.
Pearly Penile Papules
Small, dome-shaped bumps around the head of the penis. Completely normal anatomical variation present in many men. Not an STI and don't require treatment. Often confused with warts but are symmetrical and uniform.
Skin Tags
Soft, flesh-colored growths that hang off the skin. Common in areas of friction like the groin. Not contagious and not an STI. Can be removed if bothersome but aren't medically necessary to treat.
STI-Related Causes of Genital Bumps
Genital Herpes (HSV-1 or HSV-2)
Appearance: Grouped, fluid-filled blisters that break into shallow, painful ulcers. Often preceded by tingling or burning.
Key features: Painful, recurrent outbreaks in same area, flu-like symptoms in first outbreak. Manageable with antiviral medications.
Genital Warts (HPV)
Appearance: Flesh-colored, soft bumps that may be flat or raised. Often have a rough, cauliflower-like texture. Can appear singly or in clusters.
Key features: Usually painless, may itch slightly. Can be treated by healthcare provider. HPV vaccination prevents most wart-causing strains.
Molluscum Contagiosum
Appearance: Small (2-5mm), dome-shaped bumps with a shiny, pearly surface and characteristic central dimple or pit.
Key features: Usually painless, can spread to other body areas or to partners. Often self-resolves in 6-12 months but can be treated to prevent spread.
Syphilis (Chancre)
Appearance: Single, painless, round sore with raised edges and a clean base. Appears at the site of infection.
Key features: Painless (unlike herpes), heals on its own in 3-6 weeks BUT infection remains. Easily curable with antibiotics. Must be treated.
Red Flags: When to Seek Medical Care
Get Medical Attention If:
- • Painful ulcers or open sores—especially if new
- • Clustered blisters that break and weep
- • Cauliflower-like growths that are multiplying
- • Rapidly spreading bumps
- • Fever or swollen lymph nodes with genital symptoms
- • Bumps that don't heal after 2 weeks
- • New sexual partner and now have symptoms
What to Do Next
Don't Pop or Pick
Squeezing bumps can spread infection, cause scarring, and make diagnosis harder. Leave them alone.
Avoid Sexual Contact
Until you know what's causing the bumps, avoid sex to prevent potential transmission.
Take Note of Changes
Document when bumps appeared, if they're changing, and any other symptoms. This helps your healthcare provider.
Get Evaluated
If bumps are concerning, new, or accompanied by other symptoms, see a healthcare provider for proper diagnosis.
