Submarine Submersible Contracting Masturbator by OTouch

Submarine Submersible Contracting Masturbator by OTouch is an advanced stroker combining automatic thrusting, seven vibration modes, and 360° contraction in one waterproof device. It layers three separate sensations to create intensity that mimics realistic motion and grip. Ideal for anyone seeking more from a stroker than basic vibration alone.

Design and build

Submarine Submersible Contracting Masturbator by OTouch integrates three pleasure systems into a single engineered device. The stroker's internal sleeve is engineered to contract around the entire length, creating a tight, responsive grip that builds with each stroke. This contracting mechanism works alongside automatic thrusting and vibration, so all three sensations layer together rather than competing. The 600-gram weight gives it genuine heft and control, making it feel substantial in hand during use.

What distinguishes the Submarine from basic strokers is the coordination between its three systems. The thrusting mechanism doesn't just push; it mimics natural rhythms across five distinct patterns. The vibration adds depth through seven intensities. The contraction delivers the gripping sensation that transforms the whole experience. Unlike Textured Strokers that rely on internal ridges alone, the Submarine's mechanical systems create dynamic sensations that respond to your movements in real time.

Notable features

• Intelligent thrusting system: Five automated modes that mimic different natural rhythms, so you get realistic motion without doing all the physical work yourself.
• 360° automatic contraction: The entire internal sleeve grips and releases around you in real time, creating tight, satisfying sensations that respond to movement.
• Seven vibration modes: From gentle pulses to intense vibrations, each intensity builds differently and can be combined with thrusting or contraction.
• IPX7 waterproof design: Completely submersible for shower or bath use, making cleanup easy and opening up new pleasure opportunities.
• Extended battery life: Over 60 minutes of continuous use per charge, with USB recharging in two hours for reliability during longer sessions.

Getting started with a masturbators and stroker

Start by charging the Submarine fully before your first use. Apply a generous amount of water-based lubricant inside the sleeve and around the entry point; this ensures smooth, comfortable sensation during thrusting and contraction. Turn the device on using the control button and select your starting mode—most first-timers prefer a lower vibration setting paired with automatic thrusting to feel how the three systems work together. Let the device do the work initially; you can increase intensity once you understand the rhythm.

During a session, experiment with layering. Start with just vibration, then add thrusting, then activate contraction to feel how each sensation changes the experience. The device responds to your pace, so the more you move, the more intense the sensation becomes. Rinse thoroughly under warm water immediately after use, and dry completely before storage. Unlike Double Ender Strokers that require careful drying inside, the Submarine's sealed design makes post-session cleaning straightforward and quick.

Care and storage

Rinse the internal sleeve immediately after use under warm running water, working lubricant out thoroughly. For deeper cleaning, run warm water through the entry point and squeeze gently inside. Pat the exterior dry with a soft cloth, then stand the device upright to air-dry the interior completely before charging or storing. Store in a cool, dry place away from direct sunlight. Recharge every two to three months if stored long-term to maintain battery health.

This knowledge makes it easier to work out whether the Submarine's multi-sensory approach matches your preferences or whether a simpler option would serve you better.

What to expect

The Submarine feels noticeably heavier and more substantial than basic strokers, which most users appreciate for stability during use. The thrusting motion is pronounced and genuinely mimics natural rhythm rather than subtle movement; first-timers often notice immediately that this is not a vibration-only device. The contraction adds a gripping sensation that takes a few uses to fully appreciate, as it works most effectively when all three systems run together rather than separately.

Battery life exceeds 60 minutes of continuous use, which covers most sessions, though charging does take two hours. The IPX7 waterproof rating means you can rinse it under running water without concern, though the seals benefit from thorough drying before storage. The 4.5 cm diameter suits most users comfortably, though those accustomed to tighter sleeves may find it slightly roomier than expected on initial contact.

Cleaning is straightforward because the sealed design prevents water or lubricant from entering the motor housing. People who benefit low-maintenance devices appreciate that you simply rinse and dry without dismantling anything. The device is also quiet enough for discreet use, though the thrusting motor produces slightly more sound than a vibration-only stroker at higher intensities.

The learning curve is minimal—you press a button and the device handles everything automatically. Most users settle into their preferred mode combination within two or three sessions. Those who find the sensations overwhelming initially often discover that starting at lower vibration intensities makes the experience more enjoyable while they adjust to the thrusting and contraction working together.

How it compares

The bottom line

Check out the Submarine Submersible Contracting Masturbator by OTouch if you want a stroker that actually moves, grips, and vibrates with genuine coordination. This device delivers sensations that feel remarkably lifelike because all three systems work together rather than separately.
