About this product

Erection Assistant 2 8.5" Strap-on by NANMA Corporation is a hollow vibrating strap-on that combines realistic penetration with 10 adjustable vibration patterns. The curved silicone shaft sits within an adjustable harness that accommodates different body types, and the hollow interior lets you wear it while experiencing every sensation. The design sits among other realistic dildos but adds both vibration and the hollow wear-inside construction, which changes how both partners experience the moment.

The curved angle is deliberately engineered to target pleasure zones naturally, while the USB rechargeable motor runs quietly through multiple intensity levels. Waterproof silicone means cleaning is straightforward and shower play is an option. The harness stays secure throughout a session, so you can focus on sensation rather than adjustment or slippage.

The highlights

• Hollow design: You wear it and feel every thrust, vibration, and movement alongside your partner, staying fully connected throughout.
• 10 vibration modes: Adjust intensity from subtle pulses to powerful rhythms, finding the pattern that works for this session or switching mid-play.
• Curved shaft: The angle follows natural body contours and targets sensitive areas without requiring awkward positioning or guesswork.
• Adjustable harness: Securely fits various body types and stays in place during active use without pinching or loose straps.
• USB rechargeable and waterproof: No batteries to replace, full shower compatibility, and simple rinsing under warm water between sessions.

Using a realistic dildo without rushing

Start by charging the strap-on fully via USB before your first session. Adjust the harness to fit comfortably around your hips and waist—snug enough it won't slip, loose enough you can slide one finger under the straps. Apply water-based or silicone-based lubricant generously to both the shaft and your partner's entrance, and to the interior if you're wearing it. Begin with a lower vibration mode and let your body adjust to the sensation and weight before increasing intensity.

Positioning matters more than speed. The curved design works best when you move with natural hip motion rather than thrusting hard immediately. Most people find the first 10–15 minutes involve discovering which of the 10 modes feels right for this particular session, and what depth and angle suit both partners. Take breaks if the harness shifts—simply pause, readjust the straps, and resume. Unlike fixed realistic penis sleeves, the adjustable harness lets you loosen it without full removal if you need to reposition mid-session.

Should you choose this one?

Care and storage

Wash the silicone shaft and harness with mild soap and warm water immediately after each session. Pat dry with a lint-free cloth and allow the harness straps to air-dry fully before storage. Store in a cool, dark place away from direct sunlight, which can degrade silicone over time. Charge via USB monthly even if not in regular use to maintain battery health. Keep away from sharp objects and extreme heat.

What to expect

The first time you wear the Erection Assistant 2, expect a learning curve with harness adjustment. Most people spend the first 5–10 minutes getting the straps tight enough for security without restricting blood flow or comfort. Once fitted correctly, the weight is minimal and the hollow design feels natural—you're not aware of wearing anything until the vibrations begin.

Vibration intensity varies across the 10 modes more noticeably than typical vibrators. Lower modes deliver subtle pulses good for building sensation gradually; mid-range modes provide steady buzz; higher modes pulse forcefully. Most people cycle through modes during a single session to find what works in the moment. The curved shaft does target angled areas effectively, but this requires some experimentation with positioning to locate your preferred angle.

Cleaning is straightforward thanks to the waterproof build—a rinse under warm water and gentle soap takes under two minutes. The harness dries quickly if you towel-pat it. Battery life from a full USB charge typically covers multiple sessions before recharging is needed, though actual runtime depends on which vibration mode you favour.

People who return this item usually cite harness discomfort during extended sessions or prefer non-vibrating designs. Those who keep it appreciate the combination of realism, adjustability, and the fact that both partners feel the vibrations. The curved design genuinely does suit angled penetration better than straight shafts, and the hollow wear-inside feature is what sets this apart from standard strap-ons.
