My Verdict

I'm in love with the b-Vibe Expand Plug. I have been searching for years to find an anal plug that actually fit and would stay put inside my butt hole, and I have finally found it with the Expand Plug. Its ergonomic design and just right size means it's easy to get in and it stays put once inside. It also has the wonderful features of vibrating and being able to actually expand and get larger via the inflatable sack that is inside the head of the plug. Gold star to who ever came up with that idea, I love the creativeness, but sadly for a size king like myself, the expanding element doesn't really feel like much for me, and none of the vibrations are in the head of the plug, only in the base, which does nothing for me. Your milage my vary though. Overall I am still blown away by the fact that the Expand Plug, and I cannot stress this enough, ACTUALLY FITS! Because of that and the fact that the Expand Plug comes with its own discreet carrying bag, the Expand Plug has become my new favorite travel toy.

Buy, if you...

  1. Like anal play.
  2. Have a prostate and like stimulating it.
  3. Want an ergonomic toy.

Don't buy, if you...

  1. Aren't into anal play.
  2. Don't want to deal with small remotes.

Personal Experience

My Personal Experiences with b-Vibe Expand Plug

Goldie Locks and the butt plugs

I have been into all things anal for a solid decade now. In that time I have stuck many a dildo in my butt. I’ve found a bunch that I like and even more that I didn’t. In that time however, I have never found a butt plug or prostate massager that actually fits me. What do I mean by fit? I mean a toy that actually fits all the way in my butt, and stays put there. Nothing is worse than a plug that decides to fall out with every sneeze or cough. All the plugs or prostate massagers I’ve tried have been either too long or too skinny. I’ve probably  spent close to $1,000 over the years on anal toys that don’t fit. But then I found the b-Vibe Expand.

First looks

When I first unboxed the Expand plug, I wasn’t really expecting much. I was hopeful that for once a plug would actually fit me and work, but I wasn’t really expecting that to happen. The Expand looked like most other prostate massagers I’ve seen and tried in the past. Relatively bulbous head, curved body, and an elongated flared base to rub against the perineum, and a vibrator located somewhere inside the toy to send more stimulation to the prostate. Nothing out of the ordinary. What was out of the ordinary was the expand function of the plug. The Expand Plug gets its namesake from having an inflatable balloon inside the head of the plug, and with the push of a button can become inflated and bigger, effectively making it a vibrating inflatable prostate massager. I was excited to test that part out.

Putting it to the test

For me, I have a test I do with all new plugs or prostate massagers I try out. After getting the toy in, and getting an initial feel for whether or not the plug actually fits in me and feels ok, I like to do chores with said plug still in me. Cooking, cleaning, doing laundry, the basics. I do this because the act of being plugged while having something stimulate my prostate all day is a goal I’m actively working on doing more, and because wearing a plug or prostate massager during regular day to day is a great way for me to see how comfortable the plug is in different positions, how good the vibrations feel and how long they last for, and to actually feel how stimulating massagers can be on my prostate. Naturally, if I can move around freely without having to think about the toy falling out, if I can sit down and stand up without the toy hurting or being uncomfortable, and if the sensation is distracting in a good way, the toy is a keeper.

The fit was a hit

This is exactly what the Expand plug was. It stayed in me the whole time I was moving around cooking and doing laundry, the vibrations lasted a solid 2.5 hours on high, and I was wonderfully and frustratingly distracted the whole time. Having a toy that does all of that and is easy to get inside of me is a big deal and I couldn’t be happier with those aspects of the Expand Plug.

Not quite perfect

The Expand Plug is hands down a great butt plug, but that doesn’t mean it’s perfect. Ergonomically I think it is fantastic and feels great, but when it comes to its features, it’s a bit lacking for me. I’m a size queen, and the expanding nature of the Expand Plug wasn’t enough to give me any sort of extra sensation. To be honest, I couldn’t really even feel when it was expanding or contracting inside of me. The vibrations were also lacking for me. They were strong, and the battery life was enough to keep them going for a while, but the only vibrator inside of the toy was located near the tip of the base, which meant that a lot of the vibrations dissipated before they could reach the head of the toy. Even though I was disappointed that both of those features didn’t really work for me, I still love the Expand Plug. Finding a plug/prostate massager that actually fits, stays put, and is easy to get in me without any warm up or extra wahala is a big deal for me. Until I find something that checks off all of my boxes, the Expand Plug is the butt plug for me.  


b-Vibe Expand Plug Design

Aesthetically I love the design of the Expand Plug. It looks good, feels good, and it doesn't look cheap. Function wise the Expand Plug is even better. The shape of the plug made it so that it was easy to use and felt great inside of me, and while the extra features like the vibrations and expanding mode didn't really do it for me, they are well implemented and it shows that some serious thought went into designing it all.

Ease of Use

b-Vibe Expand Plug Ease of Use

As far as the general use of the Expand Plug goes, it's very easy to use, just lube it up and stick it in. Real simple. The only thing that took some getting used to was the remote that came with the toy. It's not exactly straight forward. I had to read the instructions a few times before I remembered that there is a correct sequence to turn the toy and the remote on so you can actually use the remote. I also had some issues with the vibrations settings where I couldn't change the intensity of the vibrations even though I could change everything else. In the end I'm not sure if that was a quality control issue or an overall issue with the remotes.


b-Vibe Expand Plug Quality

The b-Vibe Expand Plug is a top tier toy, and in no way does it feel cheap. The construction of the toy is well done and there are no blemishes or imperfections anywhere on it. The material is high end body safe silicone, and the vibrations feel good and strong, both signs of a quality toy.


b-Vibe Expand Plug Price

With the price ranging from $135-$170, the Expand Plug isn't what most would call a cheap toy, so is the price justified? I 100% believe the high price point is worth it in this case. Not only are you getting a quality remote controllable butt plug/prostate massager that is made of high quality material and has some very novel and interesting features, along with a wonderfully discreet (except for the zipper tassel) carrying bag, and an in depth book that goes over general butt play as well as all the ins and outs of prostate stimulation. In a time where toy companies still charge too much for cheap and some times dangerous toys, I'm more than happy to pay a little extra for a toy that I know is high quality and from a company that cares about its customers.


b-Vibe Expand Plug Performance

Did the Expand Plug live up to the expectations and promises it made online? Not really, and that's ok. Along with the usual claims that every sex toy makes, such as being the best toy ever made and making you cum instantly, b-Vibe made one bold claim that really stuck out from everything else, "The internal, expanding feature fills your sphincter and simulates the sensation of someone orgasming inside of you". Now that is a big promise to keep, and sadly the Expand Plug didn't live up to the claims for me, but I don't mind. Like I've said, the Expand Plug is still one of the best plugs I've used to this day, so I don't really mind if all the other features aren't instantly sending me into orgasmic bliss.


b-Vibe Expand Plug Packaging

The packaging the the toy was nice. It clearly showed what the Expand looked liked as well as what all was included with it. It also goes over the materials, how to charge it, the one year warranty, and it goes over the remote control and vibration modes. The only thing that I didn't like about the packaging was the size. I hate packaging waste, and there is a lot of packaging for the Expand.

Materials and care

b-Vibe Expand Plug Materials and care

The Expand Plug is made of 100% silicone, and it is splash proof, so no matter how nice it might seem to use in the bath, I wouldn't recommend it. You can clean it the same way you clean any silicone toy, either by boiling it, washing with warm soapy water, or with toy cleaner.
