Erection Assistant Vibrating Hollow Strap-On by Nasstoys

The Erection Assistant Vibrating Hollow Strap-On by Nasstoys is a hollow strap-on harness designed for men with erectile difficulties who want to maintain intimate connection and penetration. The 6-inch silicone shaft sits inside a secure harness and delivers multiple vibration patterns to stimulate both partners during sex.

What it is and how it's made

The Erection Assistant Vibrating Hollow Strap-On by Nasstoys combines a hollow silicone shaft with an integrated harness system and embedded vibration motor. The hollow interior allows your penis to sit inside while remaining engaged, whilst the rigid outer wall maintains the firmness needed for penetration. Unlike basic vibrators or simple extensions, this design addresses both the mechanical challenge of penetration and the emotional one of staying connected during sex.

The silicone is body-safe and waterproof, meaning you can rinse it under the shower and even enjoy water play. The adjustable harness uses soft, stretchy material that distributes weight evenly and stays in place without the discomfort of rigid straps. The vibration motor sits at the base, delivering sensation through the shaft to both partners.

Key features

• Hollow interior design: Lets you stay naturally involved while the rigid exterior provides consistent firmness for penetration.
• Multiple vibration settings: Customisable patterns and intensities so both partners can find what works best for them.
• Adjustable harness system: Soft straps conform to your body and stay secure throughout extended sessions without slipping or pinching.
• Waterproof construction: Body-safe silicone is easy to clean and opens up shower or bath play options.
• Simple controls: Straightforward button controls on the harness let you adjust settings without breaking the moment.

How to use a vibrating vibrator

Before use, wash the silicone shaft and harness with warm soapy water and dry thoroughly. Insert your penis into the hollow opening—the snug fit will hold it in place. Fasten the harness around your body using the adjustable straps, tightening until it feels secure but not constricting. Position yourself for entry as you normally would. Once inside your partner, press the control button to activate vibration and cycle through the settings to find the intensity that works for both of you.

During sex, the vibration will travel through the shaft to stimulate your partner internally and your external base and perineum externally. You remain in control and can adjust settings or stop vibration at any time. After sex, remove the harness and rinse both the shaft and straps under warm water, then air-dry or pat dry. For solo sessions, vibrating masturbators offer a different solo experience if you want stimulation without a partner.

Care and storage

Wash the entire harness with warm soapy water immediately after use and air-dry completely before storing. Do not submerge the battery compartment or control button in water for extended periods. Store in a cool, dry place away from direct sunlight, which can degrade silicone over time. Keep away from sharp objects and other silicone toys to prevent discolouration or damage. Replace batteries as needed.

More on the subject

Many couples find that adding vibration opens conversations about pleasure that they might otherwise avoid. The practical support this harness offers often reduces anxiety, which paradoxically makes natural function easier.

What to expect

Most first-time users find the harness surprisingly comfortable once it is adjusted properly—the key is tightening the straps firmly enough to prevent slipping without cutting off circulation. The hollow opening accommodates most erect and semi-erect states; if you struggle to stay firm, the vibration and the sensation of being held inside often helps. Take time to find the right strap tension before your first sessions with a partner.

The vibration patterns vary from gentle to intense. Start at the lowest setting and increase as you both become accustomed to the sensation. Some users notice the motor's gentle buzz in quiet rooms, while others find it adds to the experience. Battery life typically lasts several hours of continuous use, so replace batteries beforehand if you prefer not to interrupt a session.

Cleaning is straightforward—warm soapy water and air-drying take less than five minutes. The silicone is durable and shows no degradation with normal use over years. If the harness straps become loose or stretched over time, the design still accommodates adjustment, though eventually replacement may be needed.

Most couples report that the confidence boost is immediate and that the added stimulation becomes something they actively look forward to rather than a workaround. Some find it bridges the gap during periods of stress or health changes, whilst others discover they simply enjoy the extra sensation regardless.
