NJoy Pfun Plug

NJoy Pfun Plug – A Unique Prostate Massager Butt Plug

NJoy Toys is well-known for making high-quality stainless steel sex toys like the Pure Wand, a prostate massager, and the Pure Plug, a butt plug. But what happens when you combine the 2? Well, you get the Njoy Pfun Plug!

Yep, this stainless steel buttplug is designed with prostate stimulation in mind, featuring a pronounced bulbous tip that nestles against the prostate nicely. Due to its metal construction, this anal toy is heavy and extremely solid – it provides very firm pressure on the prostate.

NJoy Toys famously uses 316 medical-grade stainless steel for all of its toys, producing high-quality sex toys for men and women since 2005. While the Pfun Plug isn’t as well-known as something like the Purewand, it’s an extremely unique butt plug in its own right.

Let’s dive in!

Pros and Cons

NJoy Pfun Plug - Pros and Cons

As a steel buttplug meets prostate massage toy, the Pfun Plug has a unique set of pros and cons.

  • Compatible with any type of lube
  • Non-porous material doesn’t let bacteria inside
  • Comes in a pristine satin-lined storage box
  • Unisex but better for men due to prostate stimulation
  • ​One of the best butt plugs


  • Not ideal for all-day wear (heavy weight makes it hard to keep inside)

  • Doesn’t come in different butt plug sizes (Pure Plug has medium and small sizes)
  • Expensive

As is the case with most NJoy butt plugs, it’s hard to find things wrong with this toy! I did enjoy using it personally, though I feel like it’s a bit of a strange in-between toy that you can use for various different things. This plug has a ton of versatility, it’s just a matter of working out what’s best for you.

This thing is like the Netflix of sex toys. There are so many options, I’m not sure which to pick. Should I use it as a buttplug? Wear it during sex? Massage my prostate? I don’t know. It’ll start auto-playing trailers if I don’t hurry up.

Things to Consider With the Pfun Anal Plug

Things to Consider With the Pfun Anal Plug

Anal experience

First things first, do you have any experience with anal toys? If you don’t have any experience with anal plugs, I wouldn’t recommend starting with heavy stainless steel! Perhaps try a smaller or similar-size anal toy in silicone before moving onto this metal butt plug.

Prostate experience

In a similar vein, do you have any experience with prostate stimulation? Massaging the P-spot requires full relaxation of the muscles in your ass, which is easier said than done. This anal toy is designed to massage the prostate, so it’s helpful to know how to approach that. This is definietely one of the best butt plugs if you know how to use it.

All Day Wear

If you like to wear butt plugs under your clothes as you go about your day, you’d struggle with this toy. First off, the ring pull is very large and stiff, so it would be awkward to sit. Second, this plug is VERY HEAVY – it’s basically a large chunk of metal.

Unless you’ve got arse muscles like Arnie, you aren’t gonna keep this in all day.


Just like the NJoy Pure Plug this product is not among the cheapest sex toys on the market. You have to look at these stainless steel sex toys as long-term investments because they’re incredibly high-quality, easy to clean, and provide intense orgasms. Basically, they’re worth the money you pay!

Features and Benefits

Features and Benefits NJoy Pfun Plug

Insane orgasms

This toy nestles nicely against the prostate gland, so it can create extremely intense orgasms that other anal plugs have no hope of recreating. The sensations of pleasure radiate throughout the body, whether you’re wearing this about the house, using it during masturbation, or wearing it during sex.

Solo or couples play

Though this toy can be used for solo play, it’s also great for wearing during sex! It might flex your butt muscles more than you’re used to, but your regular penis orgasm will feel 10 times stronger with this bad boy doing its job. I found that missionary (with me on top) for the best position for keeping it inside, but feel free to experiment!

For the sake of clarity, I don’t actually know if it’s 10 times stronger. It certainly feels that way. Maybe I’ll commission a double-blind study.

316-grade stainless steel

The Pfun Plug is made from 316 medical-grade stainless steel in accordance with the NJoy philosophy to create safe, high-quality sex toys that will stand the test of time. The heavy weight and firmness of the metal also create a very unique filled-up sensation.

NJoy sex toys are really built to last. They’ll be here after the apocalypse with Cher and the cockroaches.

Ergonomic design

The 2 bulbous bumps on this toy are designed to help stabilize the buttplug and pop it into just the right place for pleasure. If you’re relaxed and in the right position, this plug will nudge your prostate easily. You really feel it as soon as it makes contact – there’s something about the firmness and the weight that help enhance those sensations of pleasure.  

Elegant Storage Box

I wouldn’t normally give a sex toy storage box its own section in a review, but the box this comes in it so bloody lovely I can’t help it! Nestled in a cushion draped with pink satin, this box is designed for presentation. Honestly, I wouldn’t be ashamed to have it on my mantelpiece. It’s like a jewelry box but for a buttplug. Brilliant.

Temperature play

Stainless steel sex toys are perfect for temperature play because steel retains temperature very well. For example, if you place the plug in a bowl of warm water or cool water for a few minutes, it will adapt to this temperature and stay that warm/cold for quite a long time before changing. The sensations of warm and cold inside your body can be VERY pleasurable.

I personally really like warming up this butt plug before use – it makes everything feel more comfortable and intense when it’s inside me.

Easy to clean

Basically all sex toy cleaning methods can be used for steel sex toys like this. Warm water and antibacterial soap are great for a standard clean, but if you want to thoroughly sanitize this and kill any pesky bacteria on the surface, try boiling it in a pan for around 10 minutes and then cooling it back down after. Boiling is a great way to kill the shit out of germs.


If you’ve looked through our lube guide, you’ll know that you can use ANY lube you want with stainless steel sex toys like this. If you’re planning on using this toy for all-day wear or long-term use, I’d recommend trying a silicone lube or oil-based lube, as it takes them a lot longer to dry up than water-based lubes.

Other Customer Reviews

Other Customer Reviews Pfun Plug

Here are quotes from some other customers’ Pfun Plug reviews from Reddit.

“At one point the toy was pressing a part of my prostate that felt like I was about to cum, but I never did. It didn't last massively long, but it was an amazing feeling. Because the device is heavy with a slight point to the top, it seems to be able to get to spots my Aneros simply cannot.”

“Staying relaxed and not trying to rush anything is key. Keep your body calm and let the waves of orgasm slowly roll over you. It takes time and it always starts off light.”

“This is no joke- my wife is now concerned that I did / will enjoy prostate orgasms more than PIV. I told her that each are different- I'm not sure if she really believed me or not. I do want to try this again, and this time keep going even longer!”
