What Is the Point of a Hollow Dildo?

A hollow dildo is a sex toy designed with an empty interior cavity that allows the wearer to insert their penis (or, in some cases, to pack a soft filler inside). From the outside, it looks like a regular dildo, but the inside is designed to fit snugly around the penis or sit comfortably against the body with a harness.

They’re usually made from soft, body-safe silicone or rubber, though firmer models also exist for those who prefer a more structured feel. Many come attached to an adjustable harness, similar to strap-ons, allowing both partners to enjoy hands-free play.

Who Uses Hollow Dildos — and Why?

There’s no single “type” of person who uses a hollow dildo. In fact, this toy has gained popularity across many groups for different reasons:

1. Couples Dealing with Erectile Dysfunction (ED)

One of the most common uses for hollow strap-ons is to help couples maintain penetrative intimacy when the wearer struggles with erection issues. The penis fits inside the hollow shaft, allowing penetration even without being hard. That means partners can stay physically connected without the pressure of “performance.”

For many men, that’s a huge relief. Instead of worrying about staying hard, they can focus entirely on pleasure and closeness. The result is often better communication and more relaxed, satisfying sex.

2. Exploring Size Play or Fantasy

Some people use hollow dildos simply to explore what it feels like to add extra length or girth. It can be a fun way to experiment with “what if” scenarios — what if the penis was a little thicker? Or longer? These toys allow couples to safely try out those fantasies without judgment or permanent change.

3. Gender-Affirming or Roleplay Scenarios

For transgender, non-binary, or gender-fluid individuals, hollow dildos can be affirming tools. They help people who may not have a penis experience penetrative sex in a way that feels natural and affirming. They also open possibilities for couples exploring gender roles or pegging dynamics, without needing a rigid, solid dildo.

4. For Fun and Variety

Sometimes, the reason is simply curiosity. Using a hollow strap-on can add novelty and laughter to a couple’s sex life — and that’s valuable in itself. A lot of people enjoy how it feels to share control or swap roles for the night.

 

How Does It Work?

The basic idea is simple: the wearer places their penis (or pelvic area) into the hollow interior, then secures the harness around their hips. Once strapped in, the dildo sits where a penis would naturally be, ready for action.

Some versions are open-ended at the tip, so the wearer can still feel friction and stimulation during thrusting. Others are completely closed, designed purely for structure and support.

Lubrication is important — both inside and outside. Applying a little lube inside the hollow area ensures comfort, while using plenty of body-safe lube on the outside enhances pleasure for the receiving partner.

What Does the Receiving Partner Feel?

From the receiver’s perspective, a hollow dildo feels much like a regular strap-on. Depending on the model, it can feel firm or flexible, and many are designed with realistic veins, contours, or even vibration functions for extra stimulation.

Some couples say it feels even better than an average dildo because of the stability that comes with a harness. It moves naturally with the body, creating a more lifelike rhythm.

 

What Does the Wearer Feel?

This varies. If the toy has an open tip or thinner walls, the wearer might feel some pressure or vibration during penetration. Some even report getting aroused simply from watching their partner’s pleasure or from the physical closeness.

But the deeper sensation is often psychological — the confidence of being able to give pleasure without worrying about performance, size, or stamina. That’s a powerful emotional boost that many find liberating.

Are Hollow Dildos Safe?

Yes, as long as you follow a few safety tips:

  • Choose quality materials. Always go for medical-grade silicone or phthalate-free materials.

  • Use lots of lube. It reduces friction and keeps both partners comfortable.

  • Clean thoroughly. Wash both inside and out with warm water and antibacterial soap after each use.

  • Mind the size. Make sure both the hollow chamber and the external size fit comfortably for both partners.

  • Communicate. As with all sex toys, open communication about comfort and boundaries is key.

Can You Stuff a Hollow Dildo?

Some users like to fill the inside with soft materials if they don’t plan to insert their penis. You can buy purpose-made silicone inserts or use something safe, clean, and body-friendly — never random household objects. Cotton or rolled towels inside a condom can work temporarily, but always make sure it’s clean and removable. Never stuff it with anything sharp, breakable, or unhygienic.

 

Common Misconceptions

“It’s only for men with ED.”
Not true. While that’s one popular use, many couples enjoy hollow dildos simply for variety, fantasy, or mutual pleasure.

“It looks weird or unnatural.”
Actually, many models are realistic and even better-designed than traditional toys. Some have suction cups, vibrating tips, or curved shafts that hit all the right spots.

“The man won’t feel anything.”
While direct physical sensation might be limited, the mental and emotional stimulation — seeing a partner enjoy themselves — can be very powerful.

 

 

Final Thoughts

So, what’s the point of a hollow dildo?
It’s a toy that bridges gaps — physical, emotional, or imaginative. Whether it’s used to manage ED, experiment with gender roles, explore size fantasies, or simply spice things up, the hollow dildo is all about connection and creativity.
