Short answer: yes — hearing a squelching or wet noise during self‑stimulation can be normal. It usually comes from lotion or natural moisture plus the movement of skin and tissue. Circumcision changes how the head (glans) of the penis is exposed, so some people use extra lubrication to reduce friction.

Step‑by‑step explanation:

• Why a sound can happen: If lotion, oil, or natural moisture is present, skin sliding over skin (or over the glans) can trap and move small amounts of fluid and air. That can produce a wet, squelching, or slapping sound. It doesn’t necessarily mean there’s a problem.
• Effect of circumcision: Circumcised penises have the glans more exposed. Over time that surface becomes drier (a normal process called keratinization), so people sometimes use extra lubrication during self‑stimulation to prevent discomfort from friction.
• Products and irritation: Some lotions and oils (especially fragranced or heavily perfumed products, petroleum‑based oils, or baby oil) can irritate sensitive skin or cause clogged pores or infections. Water‑based, unscented lubricants are generally less likely to irritate, but if there’s redness, itching, burning, or a rash, stop using the product and see a clinician.

When to be concerned and see a doctor or nurse:

• Persistent pain, bleeding, unusual discharge, swelling, or sores around the penis.
• Fever, difficulty urinating, or worsening redness that doesn’t improve after stopping a product.
• If you have questions about normal sexual development or are unsure what’s safe to use on genital skin.

If you are a parent concerned about a child: approach the topic calmly and age‑appropriately. Teach about privacy, body safety, and appropriate boundaries. If you’re worried about the child’s health or behavior, contact your pediatrician for guidance.

If you are a young person asking for yourself: it’s normal to have questions. You can talk with a trusted adult or a healthcare provider confidentially about development and safe hygiene. If you feel uncomfortable asking someone you know, many clinics and school health services offer confidential, nonjudgmental advice.

Bottom line: the noise alone is usually not harmful and is commonly caused by lubricant and movement. Pay attention to comfort and skin changes, choose gentle, unscented products if needed, and seek medical advice for any pain, abnormal symptoms, or if you want personalized guidance.
