Otouch - Submarine

What Is the Otouch Submarine Male Masturbator Toy?

The Otouch Submarine is an automatic male masturbator toy designed for adult men seeking a hands-free, motorised experience. Crafted by OTouch — a brand focused on male sexual wellness — the Submarine combines a compact, ergonomic form with a multi-mode internal motor. Sexual wellness is a recognised component of overall health and wellbeing, and devices like this are increasingly discussed openly as part of a healthy adult lifestyle. If you're exploring options for solo pleasure or looking to enhance intimacy, this device sits firmly in the category of personal wellness tools. You can also browse our condoms and sexual health collection for complementary products.

Priced at £99.99, the Otouch Submarine sits in the mid-to-upper range of automatic male masturbators available in the UK. It is sold as a non-medicated consumer device and does not require a prescription.

How Does the Otouch Submarine Work?

The device uses an internal motorised mechanism to deliver rhythmic stroking and vibration sensations. Here's how it functions:

• An internal sleeve — made from body-safe, skin-soft material — surrounds the shaft during use.
• The motor drives a stroking motion along the length of the sleeve, mimicking manual stimulation.
• Multiple speed settings and vibration patterns allow you to customise the intensity.
• The device is rechargeable via USB, making it convenient and travel-friendly.
• Controls are typically located on the body of the device for easy one-handed operation.

The combination of stroking and vibration targets penile nerve endings, which are densely concentrated along the glans and frenulum. This dual-action stimulation is what distinguishes automatic devices from passive sleeves.

Who Should Consider Using the Otouch Submarine?

This device is intended for adult men aged 18 and over. It may be particularly suitable for:

• Men exploring solo sexual wellness products for the first time.
• Those who find manual stimulation physically tiring or uncomfortable due to conditions such as arthritis or reduced grip strength.
• Men in long-distance relationships seeking a more immersive solo experience.
• Adults interested in understanding their own sexual response as part of broader sexual health awareness.

It is not suitable for use by anyone under 18, or by individuals with active genital skin conditions, open wounds, or infections in the area. If you have any concerns about your sexual health, speaking to a GP or visiting a sexual health clinic is always a sensible first step.

Is the Otouch Submarine Suitable for All Skin Types?

The inner sleeve of the Otouch Submarine is made from a body-safe, phthalate-free material designed to be gentle on skin. However, if you have a history of contact dermatitis or sensitivity to synthetic materials, it's worth doing a brief patch test on the inner wrist before full use. Always pair the device with a water-based personal lubricant — never silicone or oil-based — to reduce friction and protect both your skin and the sleeve material. You can find compatible options in our personal lubricants collection.

If you develop any redness, irritation, or discomfort during or after use, discontinue immediately and allow the skin to recover. Persistent symptoms should be assessed by a healthcare professional. For general skin concerns, our skin care range includes soothing products that may help with mild irritation.

This product is a personal wellness device, not a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is the Otouch Submarine and What Is It Used For?

The Otouch Submarine is an automatic male masturbator toy — a motorised personal wellness device intended for adult male solo use. It is not a medicinal product and does not treat, cure, or prevent any medical condition. Its purpose is to provide physical stimulation as part of healthy adult sexual expression. Sexual wellbeing is widely acknowledged as an important dimension of overall health. The NHS recognises that sexual health encompasses physical, emotional, and social wellbeing in relation to sexuality, and that open, informed access to sexual health products supports positive outcomes.

This device is used externally, applied to the penis, and operated via built-in controls to deliver stroking and vibration sensations. It is designed for single-user personal use only and should never be shared without thorough cleaning and use of a protective barrier.

What Do You Need to Know Before Using the Otouch Submarine?

Before using this device, read the following carefully. While it is a non-medicated consumer product, there are important safety considerations.

Do not use this device if you:

• Are under 18 years of age.
• Have open wounds, sores, or active skin infections in the genital area.
• Have a known allergy or sensitivity to the sleeve material (phthalate-free synthetic polymer).
• Are currently experiencing a sexually transmitted infection (STI) — seek advice from a sexual health clinic first.
• Have recently undergone genital surgery or a urological procedure — consult your surgeon before use.

Interactions and compatibility warnings:

• Do not use silicone-based or oil-based lubricants — these degrade the sleeve material and may cause skin irritation.
• Do not use in water unless the device is explicitly rated as waterproof — check your product manual.
• Do not use alongside topical anaesthetic creams on the penis, as reduced sensation may lead to unintentional injury from excessive pressure or duration of use.

If you are taking any medicines that affect circulation, sensation, or sexual function — such as antidepressants, antihypertensives, or medications for erectile dysfunction — speak to your pharmacist before use. You can also explore our men's health range for relevant OTC support products.

How Should You Use the Otouch Submarine?

Follow these steps for safe and effective use:

1. Ensure the device is fully charged before first use via the USB cable provided.
2. Apply a generous amount of water-based personal lubricant to the inside of the sleeve and to the penis.
3. Insert the penis into the sleeve opening gently, ensuring a comfortable fit.
4. Press the power button to switch the device on.
5. Use the mode and speed controls to select your preferred setting — start on the lowest setting if you are new to the device.
6. After use, power off the device and remove carefully.
7. Clean the sleeve thoroughly with warm water and a toy-safe antibacterial cleaner.
8. Allow to dry completely before storing.

What Are the Possible Side Effects of the Otouch Submarine?

As a non-medicated device, the Otouch Submarine does not carry the same side effect profile as a medicine. However, physical side effects from use are possible, particularly with incorrect use or without adequate lubrication.

Common side effects:

• Mild skin redness or friction irritation if insufficient lubricant is used.
• Temporary sensitivity or tenderness after prolonged use.
• Mild chafing around the shaft or glans.

Less common side effects:

• Contact dermatitis in individuals sensitive to the sleeve material.
• Bruising or oedema from excessive suction or pressure — particularly if used at high intensity for extended periods.
• Numbness or reduced sensitivity following very frequent use — this is typically temporary.

If you notice persistent redness, swelling, or any signs of infection, stop using the device and seek advice from your GP or a sexual health clinic. The NHS provides guidance on genital skin conditions and sexual health concerns via NHS.uk.

How Should You Store the Otouch Submarine?

Proper storage extends the life of the device and maintains hygiene between uses. Follow these guidelines:

• Store in a cool, dry place away from direct sunlight and heat sources.
• Keep in the original packaging or a dedicated storage pouch to prevent dust accumulation.
• Ensure the device is fully dry before storing to prevent mould or bacterial growth inside the sleeve.
• Store away from children and pets.
• Do not store in contact with other sex toys made from different materials — chemical reactions between materials can degrade both products.
• Charge the battery to approximately 50% if storing for an extended period, to preserve battery health.
