Erection Assistant 2 9.5" Strap-on by NANMA Corporation

Erection Assistant 2 9.5" Strap-on by NANMA Corporation is a hollow vibrating strap-on designed for hands-free stimulation with adjustable harness support and multi-speed vibrations. It combines realistic length with customisable intensity, making it suitable for solo use or partnered play where extension and vibration work together.

What you're getting

Erection Assistant 2 9.5" Strap-on by NANMA Corporation is built with a hollow silicone shaft that sits over the penis, delivering both extension and internal vibration simultaneously. The realistic design mimics natural contours whilst the adjustable harness secures everything in place without slipping during movement. Unlike fixed Realistic Dildos, this strap-on's hollow construction means vibrations transmit through the entire shaft rather than against external surfaces alone.

The multi-speed vibration motor runs on batteries and responds to user controls, letting you shift from gentle teasing to intense pulsing without interruption. Straps adjust to fit different body types comfortably, and the whole assembly stays secure during extended wear. This combination of realistic size, hollow design, and customisable vibration creates a sensation that neither extension nor vibration alone can deliver.

What stands out

• Hollow vibrating design: Vibrations pulse through the interior as well as the exterior, creating multi-directional stimulation that solid alternatives cannot match.
• Realistic proportions: The 9.5-inch length and 1.5-inch diameter deliver authentic sensations without exaggeration or uncomfortable extremes.
• Adjustable harness: Straps conform to different body shapes and sizes, staying put during movement without cutting off circulation or causing discomfort.
• User-controlled intensity: Multi-speed settings let you match vibration to your mood and rhythm, from subtle to powerful in moments.
• Body-safe silicone: Soft, flexible material that feels natural against skin and responds to warmth and pressure without degrading.

How to use a realistic dildo safely

Prepare by washing the silicone shaft thoroughly with warm soapy water and drying it completely. Apply a water-based lubricant generously to both the shaft and the opening to reduce friction and improve sensation. Start with the vibration set to its lowest speed whilst you adjust the harness straps to sit snugly without cutting off blood flow—you should be able to slide one finger comfortably under any strap. Take time to relax and position yourself comfortably before gradually increasing vibration intensity.

During use, check that straps remain secure and adjust them if you notice slipping or bunching. If you experience discomfort, numbness, or unusual pain, stop immediately and remove the harness. After each session, clean the shaft with warm soapy water and allow it to air dry before storage. Unlike Realistic Penis Sleeves, this hollow design requires extra attention to interior drying to prevent moisture buildup inside the shaft.

Who gets on with it

Care and storage

Wash the silicone shaft with warm soapy water immediately after use, then dry it thoroughly with a lint-free cloth. Pay particular attention to the hollow interior by running water through it and standing it upright to air dry completely. Store the harness separately in a cool, dry place away from direct heat or sunlight. Keep batteries removed during long-term storage to prevent leakage inside the motor housing.

What to expect

The hollow silicone shaft sits comfortably over the penis, and the multi-speed vibrations activate throughout the entire length once you power on the motor. First-timers often find the combination of extension and internal vibration more intense than either sensation alone—starting at the lowest setting helps you adjust to the dual sensation without overwhelming.

Harness adjustment takes a few minutes the first time, but once you find your correct strap tension, subsequent sessions require minimal fiddling. The silicone feels warm and flexible in your hands, and vibrations transmit smoothly without chattering or stuttering. Most people report that the realistic 9.5-inch length feels natural rather than extreme, and the 1.5-inch diameter accommodates comfortably without excessive stretch.

Cleaning the hollow design requires running warm soapy water through the interior and standing it upright to air dry fully—this prevents moisture or mildew buildup inside the shaft. Battery life typically runs 45 minutes to an hour of continuous use at higher speeds before the motor begins to fade. The adjustable harness accommodates a wide range of body sizes, though men with very large or very small frames may need to adjust straps beyond their normal range.

Long-term durability is solid if you rinse promptly after use and store the batteries separately during extended downtime. The silicone does not degrade quickly with normal care, though the elastic in the harness straps may gradually lose tension after 12 months of regular use.
