Submarine vs Pleasure Engine: Which OTOUCH Automatic Male Masturbator Is Right for You?

If you've been shopping around for an automatic male masturbator, you already know the struggle. Half the products out there slap the word "automatic" on the box and then give you nothing but vibration in a plastic shell. It's frustrating, and honestly, a bit insulting.

OTOUCH makes two devices that actually take that word seriously  the Submarine, a fully waterproof automatic thrusting masturbator, and the Pleasure Engine, a 3-in-1 auto thrusting, vibrating, and heating male stroker.

On paper, they look like they're playing the same game. In reality, they're built for two pretty different guys. Let's break it down.

The Submarine: Made for Water, Made for Thrust

The OTOUCH Submarine starts with one simple but stubborn idea: an automatic male masturbator shouldn't force you to stay dry.

It carries a real IPX7 waterproof rating  meaning it can be submerged up to 1 meter for 30 continuous minutes. That's not a vague "water-friendly" claim. It's an actual, testable engineering standard. Shower, bath, or a quick rinse after you're done   it's rated for all of it.

Where the Submarine really pulls ahead is motion. It's a true automatic thrusting masturbator, with 5 distinct thrusting modes that deliver real mechanical back-and-forth strokes. Not a buzzing sensation dressed up as movement. Actual thrusting.

On top of that, you get:

• 360° contraction  both manual and automatic, tightening from every direction
• 7 vibration modes  these stack with thrusting and contraction instead of replacing them

So you've got three independent functions working together. And because the thrusting and contraction are automated, it's genuinely built for hands-free sessions  not just hands-free vibration like most competitors.

Best for: Guys who want a waterproof masturbator that performs in the shower or bath, and who care most about real thrusting motion.

The Pleasure Engine: Three Functions, Total Control

The OTOUCH Pleasure Engine takes a completely different approach. Instead of specializing in water and thrust, it specializes in versatility.

It's a 3-in-1 male masturbator  automatic thrusting, vibration, and heating, each one running independently or stacked together. That means:

• Run thrusting alone for deep, rhythmic strokes
• Add vibration for layered intensity
• Switch on heating to bring the chamber to body-close warmth
• Or run all three at once and just let the device take over

Heating is the one most male masturbators skip entirely — and it's honestly the feature that changes realism the most. A warm chamber feels lifelike in a way a cold silicone sleeve just can't match.

Control is handled by a 4-way joystick on top of the device. One thumb navigates every function, mode, and intensity level without fumbling around or breaking the moment. Inside, a soft silicone chamber is shaped and textured for lifelike sensation, paired with smooth, rhythmic automatic strokes.

Best for: Guys who want maximum variety  thrusting, vibration, and heat  and who value one-handed precision control.

Head-to-Head Comparison

Go with the Submarine if:

• You want a waterproof automatic male masturbator you can actually use in the shower or bath

The Bottom Line

Both the Submarine and the Pleasure Engine solve the same core problem: most "automatic" male masturbators aren't actually automatic. The difference is in the trade-off.

The Submarine trades extra features for true waterproof engineering and genuine thrusting power  the best pick if water play and real stroke motion are non-negotiable for you.

The Pleasure Engine trades water ratings for three stacked functions and joystick precision  the best pick if you want heat, vibration, and thrusting all in one device.

Neither one is the "better" toy. They're built for two different guys. Figure out which one you are, and the decision basically makes itself.
