What you're getting

The 8 Inch Hollow Strap-On Erection Assistant by Nasstoys is a silicone dildo system that sits over your penis while an adjustable harness holds it secure. The hollow core design means your own anatomy stays involved and connected during sex, giving you sensation and feedback while the extension adds visible length and girth. Unlike solid dildos worn externally, this keeps your penis inside the shaft, so you feel everything happening.

The harness uses stretchy straps that adapt to different body shapes and sizes, distributing pressure evenly without pinching or slipping. Phthalate-free silicone is smooth, realistic, and responds naturally to movement. The 8-inch length provides substantial improvement without becoming unwieldy, and the 1.5-inch diameter adds real visual and tactile difference without discomfort.

Main features

  • Hollow core design: Your penis sits inside the shaft, so you stay connected and feel sensations throughout sex.
  • Adjustable harness: Stretchy fabric straps mould to your body and hold the dildo firmly in place hands-free.
  • Phthalate-free silicone: Smooth, lifelike texture that feels natural against skin and responds realistically to movement.
  • 8-inch length with 1.5-inch diameter: Noticeable improvement that adds both length and girth without overwhelming bulk.
  • Secure positioning: Harness design keeps everything stable during active sex, so you focus on sensation rather than adjustments.

Specifications

  • Insertable length: 8 inches from base to tip.
  • Diameter: 1.5 inches across the widest point of the shaft.
  • Material: Phthalate-free silicone dildo, stretchy polyester harness straps.
  • Weight: Approximately 120 grams (silicone shaft only).
  • Closure: Adjustable elastic straps with no buckles or fastenings.
  • Box contents: One silicone dildo shaft, one adjustable harness, one instruction card.
  • Colour: Realistic flesh tone.

Getting started with a hollow dildo

Start by washing the silicone shaft and harness in warm water with toy cleaner, then air dry completely. Put on the harness first, adjusting the straps so they sit comfortably around your body without pinching. Slide your penis into the hollow core, then pull the harness snug so the dildo sits at the angle and position you want. Use a quality water-based or silicone-based lubricant inside the shaft to reduce friction and increase comfort.

Begin slowly to let your body adjust to the sensation and weight of the extension. Most people find the harness stays secure once properly fitted, but you can loosen or tighten the straps during sex if needed. After use, apply more lubricant if sensation dulls or discomfort builds. When exploring with a partner, communicate about what feels good—many people find realistic masturbators helpful for building confidence before trying a full harness system.

Right fit or not?

This suits men wanting performance confidence and couples exploring improvement together; realistic penis sleeves offer a simpler alternative if you prefer not to use a harness.

Great if you…
  • Want to add length and girth while staying connected during sex.
  • Seek a confidence boost without losing sensation or control.
  • Prefer hands-free wear so you can focus on movement and intimacy.
  • Have a partner and want to experiment with improvement together.
Maybe not if you…
  • Find harnesses uncomfortable or restrictive against your skin.
  • Prefer a simpler product without straps to adjust or maintain.
  • Have a very short penis and find difficulty keeping an erection—the added weight may not suit you.
Always use water-based or silicone-based lubricant inside the hollow shaft to reduce friction, and check the harness straps regularly to ensure they are not cutting off circulation. Safety first. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Stop use and seek medical advice if you experience pain, numbness, swelling, discolouration, bleeding or persistent irritation.

Care and storage

Wash the silicone shaft and harness separately in warm water with a dedicated toy cleaner after each use. Dry both thoroughly with a lint-free cloth or allow them to air dry completely before storage. Store in a cool, dry place away from direct sunlight and heat, ideally in a breathable pouch. Keep the shaft away from other silicone toys to prevent sticking, and avoid storing near petroleum-based products or silicone lubricant, which can degrade the material over time.

Background reading

Understanding how hollow systems work and why they appeal to many users helps you decide if this product suits you. A hollow dildo keeps you involved in the sensation while adding visible improvement—a different approach from solid sleeves or full role-swap harnesses.

What to expect

by Risetob

The hollow design does add noticeable length and girth, but the real difference comes from the psychological boost and sustained performance confidence it provides. Most users report that once the harness is fitted properly, it stays secure throughout sex without constant adjustment. The silicone shaft is firm enough to hold its shape but flexible enough to move naturally with your body.

First use often feels different because the weight and extension take adjustment—your body needs a few minutes to register the new sensation. Some people find the harness straps press slightly where they sit initially, but discomfort usually fades after a few minutes once you relax into wearing it. The realistic texture means partner feedback is genuinely positive, which itself boosts confidence.

Longevity is good if you clean thoroughly after each use and store it away from heat and direct sunlight. The silicone shaft lasts years with regular care, though harness straps may gradually lose elasticity over very heavy use. Most people find they use this regularly once they adjust to how it feels, making it a worthwhile addition rather than a novelty.

One honest limitation: if you struggle with erection maintenance, the added weight may make things harder rather than easier. Similarly, if your penis is significantly shorter than average, keeping an erection inside the hollow core can be challenging. Start with a water-based lubricant on your first attempt—it washes off easily and helps you see whether the fit works for you before committing to regular use.

Hollow strap-on (this product) Your penis sits inside the shaft; harness holds it in place hands-free. Men wanting improvement while staying connected and involved. Keeps you feeling sensation; adds length and girth together.
Solid penis sleeve Slides over the outside of your penis; simple one-piece design. Quick, straightforward improvement without harness setup. No harness to adjust; simpler to put on and remove.
Full role-swap harness Dildo attaches externally; you wear the harness for partnered penetration. Complete role reversal and hands-free partnered sex. External positioning only; partner receives penetration, not both partners together.
Vibrating strap-on Battery-powered dildo with harness for hands-free vibration during sex. Couples wanting added sensation and internal stimulation together. Adds vibration; requires battery and charging; usually solid rather than hollow.
