TOUCH SUBMARINE – IPX7 Waterproof Male Masturbator with Auto Thrusting, Vibration, 360° Contraction & Detachable Extension Sleeve

Most male masturbators stop at the bathroom door. The OTOUCH SUBMARINE is built for what’s inside — and now for every size.

Fully IPX7 waterproof and submersible up to 1 meter, the SUBMARINE is designed for shower sessions, bathtub use, and anywhere you want water-safe pleasure without compromise. The latest upgrade adds a detachable extension sleeve, giving longer users extra length and deeper immersion while keeping the same powerful triple stimulation.

Three Functions + Extended Fit. One Immersive Experience.

SUBMARINE doesn’t ask you to choose — it delivers all three at once:

5-mode automatic thrusting delivers smooth, rhythmic strokes that replicate natural motion
360° contraction tightens around you from every direction for a gripping, immersive squeeze
7 vibration modes add intense sensation across the full length

Run them independently or stack all three. The new detachable extension sleeve easily attaches to accommodate longer sizes, ensuring full coverage and maximum pleasure for every user.

IPX7 Waterproof — Built for the Bath, Shower & Beyond

While most competitors offer only basic splash resistance, SUBMARINE is engineered for true underwater use. Submerge it up to 1 meter in the bath or take it into the shower without hesitation. The same waterproof seal that protects it during play also makes cleaning effortless — just rinse under running water after every session.

Premium Build, Powerful Performance

IPX7 waterproof — fully submersible up to 1 meter
5 thrusting modes + 7 vibration modes + 360° contraction — triple stimulation, fully stackable
Detachable extension sleeve — designed for longer sizes, easy to attach and remove
1000mAh battery — 60+ minutes of continuous use per charge
Silicone + ABS construction — premium body-safe materials
USB rechargeable — convenient charging, ready when you are
< 65dB noise level — quiet enough for private sessions

Whether you’re looking for a waterproof male masturbator, an auto thrusting stroker, or a shower-safe sex toy with extension sleeve, the OTOUCH SUBMARINE delivers deeper, longer, and more intense pleasure — now sized for everyone.

1) How to choose the right toy

Start with your goal: gentle relaxation, stronger intensity, targeted stimulation, or hands-free use.
Beginner-friendly picks: smaller/medium size, multiple intensity levels, and a simple shape (easy to control).
Couples: look for quiet, remote/app control (optional), and designs that don’t get in the way.

2) Materials that feel better (and are safer)

Body-safe silicone (smooth, soft, easy to clean) is the most popular.
Avoid mystery materials. If you’re sensitive, choose non-porous materials (silicone, stainless steel, glass) and always clean before/after use.
If you have allergies/skin sensitivity, patch-test by touching the material to your skin first.

3) Power, noise, and waterproofing

USB rechargeable = convenient and usually stronger than battery-only.
If you need privacy, choose low-noise models and check reviews/specs.
Water resistance vs waterproof: waterproof is easier for cleaning and shower use but always follow the rating (e.g., IPX6 is strong water resistance, not full submersion).

4) Lube compatibility (important!)

Water-based lube works with almost everything and is the safest choice for silicone toys.
Silicone-based lube can damage some silicone toys over time (unless the brand says it’s compatible).
Use more lube if there’s any friction—comfort first.

5) Cleaning, storage, and sharing

Wash before and after: warm water + mild soap or toy cleaner, then dry fully.
Don’t share without protection: if sharing, use a fresh condom on the toy and change it between partners/uses.
Store in a clean pouch/box, away from dust and away from other toys (some materials can react when touching).

6) Safety basics

Start on low intensity, go slow, and stop if there’s pain, numbness, or irritation.
For any toy designed for deeper insertion, make sure it has a wide/flared base (this is a key safety feature).
If you’re pregnant, have a medical condition, or experience persistent pain, check with a clinician.

Q1: What makes the SUBMARINE different from other male masturbators?
Most toys only offer vibration or basic suction. The SUBMARINE combines true IPX7 waterproofing (fully submersible up to 1 meter), 5 automatic thrusting modes, 7 vibration modes, and 360° contraction that squeezes you from every direction. Now it also comes with a detachable extension sleeve, so even longer sizes can enjoy full, deep stimulation. It’s designed for the shower, bath, or bed — no compromises.

Q2: How does the thrusting and contraction actually feel?
The 5 thrusting modes deliver smooth, rhythmic strokes that feel like real motion, while the 360° contraction (both manual and automatic) tightens around you for a firm, immersive grip. You can use them separately or stack them together. Many users say the combination feels much closer to real intimacy than single-function toys.

Q3: How customizable are the vibrations?
There are 7 distinct vibration modes that run along the full length of the sleeve. You can use vibration alone, or layer it with thrusting and contraction for deeper, more intense sessions. Everything is controlled with simple buttons, so you can adjust on the fly.

Q4: Can I really use it in the shower or bathtub?
Yes. The SUBMARINE is fully IPX7 waterproof and can be submerged up to 1 meter. It’s built for wet play in the shower or bath, and cleaning is as simple as rinsing it under running water afterward. No special care required.

Q5: How long does the battery last and how do I charge it?
The 1000mAh battery gives you over 60 minutes of continuous use on a full charge. It charges via USB, so you can power it up with a power bank, laptop, or regular charger — convenient and ready whenever you are.

Q6: What is it made of? Is it body-safe?
It uses soft, premium body-safe silicone for the inner sleeve and durable ABS for the outer shell. All materials are phthalate-free and designed for comfortable, skin-friendly use. The new detachable extension sleeve is also made from the same soft silicone, so it feels consistent and safe.

Q7: Is it suitable for longer sizes?
Yes. We’ve added a detachable extension sleeve specifically for users who need extra length. It easily attaches and removes, giving longer sizes full coverage and deeper thrusting without sacrificing the original intensity or waterproof performance.
