Hollow Strap-On Dildos: How to Choose & Use Them (Great for ED)
Hollow strap-on sets have been around for decades. In fact, they are one of the oldest commercially made pleasure products, designed as prosthetic penis attachments for men suffering from ED and marketed to doctors who would recommend them as “marital aids.”
Although the quality, materials, and styles have changed significantly over the years, hollow strap-ons are still incredibly popular. Whether you’re navigating ED, exploring new dynamics, or simply curious, this guide will walk you through how hollow strap-ons work, how to choose the right one, and how to use them in a way that feels good for both partners.
What Is a Hollow Strap-On Dildo?
Unlike traditional solid dildos, hollow strap-ons are designed with an opening and a hollow center, allowing them to be worn over existing anatomy. They are structured and hold their shape, which means they can be worn with or without an erection, as well as by any gender. The difference between a hollow strap-on and a penis extension is primarily in the firmness and the presence of a strap system.
Penis extensions are usually soft and stretch over the penis to increase length or girth. They are either held up solely by the wearer’s own erection, or with some help from a strap that goes under the testicles to help keep the extension in place. We at Betty’s typically don’t recommend a penis extension if you are experiencing ED or erectile issues since they don’t stay in place well without an erection to hold them up.
Hollow strap-on systems are also fantastic for increasing girth and length if that is something you want to experience, since they come in a wide array of colors, shapes, and sizes..
Why Hollow Strap-ons Are Especially Helpful for ED
Erectile dysfunction is incredibly common and it can affect confidence just as much as it affects the body. While there are endless options for pills, creams and supplements on the market, hollow strap-ons offer a different kind of support by completely taking away the stress and pressure to perform. Instead of relying on an erection alone, they create:
-
Consistent structure and shape
-
Reliable penetration without a timeframe
-
More control over movement and rhythm
-
A shift from performance to connection
They can also help reduce anxiety around maintaining an erection, allowing both partners to stay present and enjoy the experience.
Not Just for ED: Designed for Every Anatomy
While they’re especially helpful for ED, hollow strap-ons are for anyone who wants:
-
Added length or girth
-
A firmer feel during penetration
-
More control or consistency
-
A different dynamic in partnered play
They can be used by people of all genders and bodies, and in many cases, they open the door to new kinds of pleasure and confidence.
How to Choose the Right Hollow Strap-On
This is where a lot of people get stuck, but it doesn’t have to be complicated.
1. Fit Comes First
The internal opening (or sleeve) should feel:
-
Snug but not tight
-
Comfortable against the body
-
Supportive without restricting circulation
Many styles are flexible, but sizing still matters, especially for comfort over time. You can also look at whether or not there is a bumper or padding that rests against your pelvis to avoid discomfort.
2. Consider Length & Shape
Think about what will feel good for your partner. Talk to them about whether they want to experiment with a larger size or maybe with added vibration. Keep in mind:
-
A moderate length is often best to start
-
Slight curves can help with targeted stimulation
-
A smoother shape can feel more comfortable for beginners
-
A soft tip will be more comfortable if your partner is more sensitive
3. Material Matters
Two common materials found in hollow strap-on dildos are PVC and Silicone.
PVC is more rigid and firm. This is the material often found in large hollow dildos because it will keep its shape. This will also feel harder to your partner, so keep that in mind.
Silicone is our preferred material for hollow strap-ons here at Betty’s because it is:
-
Body safe and non-porous
-
Safer and more hygienic for your partner
-
Can be thoroughly disinfected if you want to go between partners or between anal and vaginal play
-
Easy to clean
-
Soft yet supportive
4. Harness vs. All-in-One
Some hollow dildos use an o-ring and harness system like other strap-ons. This may be appealing to you because the dildo can be removed for thorough cleaning or for other play. You can also place other dildos in the harness for a variety of options.
Alternatively, some systems have a dildo permanently attached to the harness. This can be more stable, particularly if you are using a larger size dildo. The drawback is that it is slightly more awkward to clean.
How to Use a Hollow Strap-On Comfortably
This is where everything comes together and where confidence really builds.
1. Start With Communication
We recommend shopping for your hollow strap-on together. Read the descriptions, look at the pictures, and browse. Especially when ED is part of the experience, reassurance and communication matter. Talk about:
-
What feels good
-
What size you want to try
-
What you’re curious to try
-
What pace feels right
2. Take Your Time Getting Set Up
-
Make sure the fit feels secure
-
Adjust the harness if needed
-
Use personal lubricant inside and outside for comfort
-
Make sure your partner is also sufficiently lubed up and ready
This step alone can make a huge difference.
3. Focus on Movement, Not Performance
The best part of using a hollow strap-on is that you can relax in both your body and mind. You don’t need to perform or worry about maintaining and erection, you can just enjoy the sensations with your partner.
-
Try a partner on top position to allow them to control speed and depth of penetration
-
Grind your hips rather than thrusting
-
Go slowly at first
-
Let your partner guide the pace
4. Prioritize Comfort for Both Partners
For the wearer:
-
Make sure there’s no pinching or pressure
-
Adjust positioning as needed
For the receiving partner:
-
Start slow and build gradually
5. Stay Connected
Eye contact, touch, and check-ins go a long way. This isn’t about replacing anything, it’s about expanding what’s possible together.
Common Concerns (You’re Not Alone in These)
“Will it feel natural?”
Hollow strap-ons are enclosed, which means you won’t be able to feel your partner the way you are accustomed to. It can take a little getting used to but many people find it becomes intuitive quickly. Adding lubricant to the inside of the dildo lets you to feel its warmth and wetness and allows you to create a stroking effect on your own penis inside the shaft.
“Will my partner still feel connected to me?”
Absolutely. You can still perform in the positions you both love. In many cases, it actually enhances connection by removing pressure to perform and allowing more presence.
“What if I feel self-conscious?”
That’s completely normal. Remember that your partner wants to be with you and this is a fun experience you can have together. Have them help you put it on and spread the lubricant on both of you. Lots of foreplay if key. Take it slow, keep communication open, and remember, this is about pleasure, not perfection.
A Different Way to Think About Intimacy
Hollow strap-ons aren’t about replacing something. They’re about expanding your options. They allow you to:
-
Stay connected
-
Regain intimacy
-
Explore new sensations
-
Take pressure off performance
-
Focus on what actually feels good
And for many people, that shift changes everything.
