Frequently Asked Questions

An automatic masturbator (also called an auto stroker or hands-free masturbator) is a motorized device that simulates oral, vaginal, or anal stimulation using suction, vibration, and thrusting motions. OTOUCH models feature patented AIRTURN suction technology with automatic active clamping for a realistic, hands-free experience.

AIRTURN series focuses on suction + vibration with OLED smart display. The AIRTURN 4 features 7 suction + 7 vibration modes with second-gen clamping tech.

INSCUP series features automatic active clamping that wraps around the shaft. The INSCUP 4 adds a magnetic privacy lock with key access and manual clamping control.

For beginners, the AIRTURN 2 is our top pick — 6 vibration modes, 5 suction modes, OLED display, and dual heating at an accessible price.

Budget option: CHIVEN 2 — 6 vibration modes, IPX6 waterproof, under $76.

All OTOUCH masturbators operate at less than 60dB — quieter than a normal conversation (60–65dB). The Submarine and YU BattleHelm are slightly higher at <65dB. All models are designed for discreet, apartment-friendly use.

All products use body-safe, phthalate-free materials:

• Silicone exterior — skin-like, hypoallergenic
• TPE inner sleeve — soft, removable, easy to clean
• ABS body — durable, medical-grade plastic

All models are CE, FCC, and RoHS certified.

1. Remove the TPE inner sleeve from the device body
2. Rinse under warm water with mild antibacterial soap
3. Use the Masturbator Rinser for deep cleaning
4. Dry completely with the Chamber Dryer
5. Wipe device body with damp cloth (don't submerge non-IPX7 models)

Use water-based lubricants — safe with silicone and TPE, easy to clean, compatible with all models.

Avoid silicone-based lubricants — they can degrade the TPE inner sleeve over time.

The Auto Heating Rod warms lubricant to 36°C–46°C for a more realistic feel.
