Foreskin

The foreskin (also called the prepuce) is a fold of skin that covers and protects the head (glans) of the penis. It's attached at birth and can be pulled back to expose the glans underneath. Some people have their foreskin removed through circumcision, so not everyone has one — both are normal.

• The foreskin covers and protects the glans (head) of the penis.
• It's packed with nerve endings, making it one of the most sensitive parts of the penis.
• It retracts (pulls back) naturally during an erection and can be pulled back for cleaning.
• Some people have it removed (circumcision) for medical, religious, or cultural reasons.
• A foreskin that's too tight to retract is called phimosis — it's common in younger children and usually resolves, but can sometimes need treatment.

What it does

The foreskin isn't just spare skin — it has a few functions. It protects the sensitive glans from friction and drying out. It contains a high concentration of nerve endings, contributing to sexual sensation. And it produces natural oils and moisture that keep the glans smooth and lubricated.

During an erection, the foreskin usually retracts on its own, exposing the glans. During masturbation or sex, the movement of the foreskin over the glans is part of what creates stimulation.

Cleaning

If you have a foreskin, washing underneath it is part of normal hygiene. Gently pull it back and rinse with warm water — that's it. You don't need soap under the foreskin (it can irritate the sensitive skin), and you definitely don't need any special products.

If you don't clean under the foreskin regularly, a whitish substance called smegma can build up. Smegma is a mix of dead skin cells and natural oils — it's not dangerous, but it can smell and look unpleasant if it accumulates. Regular washing prevents this.

When the foreskin is tight

In babies and young children, the foreskin is attached to the glans and can't be pulled back — that's normal and it separates naturally over time. By the time most people reach puberty, the foreskin should retract easily.

If the foreskin is still too tight to pull back by your mid-teens, or if pulling it back is painful, that's called phimosis. It's quite common and usually treatable. Options include gentle stretching over time, steroid creams prescribed by a GP, or in some cases, circumcision. Another condition called paraphimosis happens when the foreskin gets stuck behind the glans and can't be pulled forward again — this can cut off blood flow and needs medical attention quickly.

Things people get wrong

"You need to forcibly retract a child's foreskin to clean it." No — forcing back a foreskin that isn't ready can cause pain, tearing, and scarring. It separates naturally. For young children, external washing is enough.

"Having a foreskin is unhygienic." Not if you wash. An uncircumcised penis that's washed regularly is just as clean as a circumcised one.

"The foreskin doesn't do anything." It protects the glans, keeps it moist, and has a high concentration of nerve endings that contribute to sensation.

Things people ask about the foreskin

Is it normal if my foreskin doesn't pull all the way back yet?

If you're still going through puberty, it might just need more time. If it's causing pain, tightness, or difficulty, mention it to a GP — they can advise on whether treatment would help. It's a very common issue and nothing to be embarrassed about.

Does it matter if I have one or not?

No. Both circumcised and uncircumcised penises work the same way. Sensitivity might differ slightly, but there's no evidence that one is "better" than the other.

What's the white stuff under my foreskin?

That's smegma — a buildup of dead skin cells and natural oils. It's harmless but can smell if it accumulates. Regular washing under the foreskin sorts it out.

Can the foreskin tear?

It can, usually from rough handling, insufficient lubrication during sex, or phimosis. Small tears (frenulum tears are the most common) can bleed a fair bit but usually heal on their own. If it keeps happening, see a GP.

Where to get help

• Your GP — for phimosis, paraphimosis, or any concerns about your foreskin. They deal with this regularly.
• NHS 111 — for advice on whether something needs urgent attention, especially if the foreskin is stuck (paraphimosis).

The foreskin is a loose fold of skin that covers the tip (head) of the penis. Not everyone has one — some people have it removed through an operation called circumcision, for medical, religious, or cultural reasons. Both having a foreskin and not having one are normal.

The foreskin protects the sensitive tip of the penis and keeps it moist. It's full of nerve endings, so it's very sensitive to touch. During an erection, it usually slides back on its own to uncover the tip.

If you have a foreskin, you need to wash underneath it regularly. Gently pull it back and rinse with warm water. You don't need soap under there. If you don't wash under it, a whitish stuff can build up. It's not harmful but it can smell. Regular washing stops this.

In young children, the foreskin can't be pulled back — that's normal. It loosens by itself over time. By the time you're a teenager, it should pull back easily. If it's still too tight or hurts when you try to pull it back, a doctor can help. It's a very common thing and nothing to be embarrassed about.

If the foreskin ever gets stuck behind the tip and you can't get it back, that needs medical help quickly.
