BIG and I mean BIG plug!

This is a huge toy, so beginners stay away, but if you feel up to the challenge of inserting a colossus into your bum then this can be a great toy. It is made of high quality silicone and has a unique texture that can provide some very interesting sensations. A great toy if you are looking for a step up from a 2.0 diameter toy.
-Massive Stimulation
-Unique Texture
-An Advanced User Toy
-None other than its size

extremely useful review


The Big Man by Doc Johnson is a silicone butt plug. It is meant to be inserted into your bum and provide stimulation there. It has ridges designed specifically for prostate stimulation, but they would feel pleasant in a female too. They are going to provide stimulation if you do not have a prostate. This toy is a butt plug, so you simply insert it and leave it. But you are going to feel this thing. You are going to have a filling sensation and some massive pressure. It is big, it is filling, it presses on your prostate.

Because of the sheer size of this toy it could be used vaginally with good results. The ridges could probably provide some good G-spot stimulation. The only major drawback would be the toy could be too short for some people. But I think it would be reasonable to buy this as a butt plug, but try it out as a vaginal toy as well. It actually might be too big for some people vaginally.

This is an advanced users toy hands down. I have played with some bigger anal toys such as the Pure Plug 2.0, but this one was hard to fit. You have to know how to relax your muscles. You need to know how to slowly warm up, and you need to be used to large toys, because this toy is just huge. If you have never had a 2 diameter plug in you then do not think about buying this toy.

The toy has a nice large base to it, so there is no worry of getting this toy lost in yourself. It is very safe.

Material / Texture

The Big Man is made out of 100% food grade silicone. Silicone is one of my favorite toy materials for a lot of reasons. Firstly it is extremely body safe. It is hypoallergenic, latex free, phthalate free, and non-porous. Because it is non porous it is extremely easy to clean. You can use just soap and water In porous materials bacteria can live in the pores and then it is impossible to clean, because sometimes the soap and water will not reach them. With a non-porous material there can only be bacteria on the surface of the toy, so cleaning with soap and water will kill all of them. The toy has no odor and no taste (if you have just washed it of course) which is nice. If I am going to use a toy anally I do not want it to retain any odor. Silicone is rated a 10/10 on EF's safety rating and for good reason. Silicone is a great material.

Doc Johnson's silicone seems to be a bit tackier or stickier than other company's silicone. I thought it might be less enjoyable, but I found once it was lubricated there was no difference. If you run your hand across the toy you feel more drag, but with lube there is no difference. Their silicone also tends to be a bit more firm than other company's (compared to Fun Factory and Tantus). I actually think this is a good thing with an anal toy. It can be hard to insert an anal toy if the toy is extremely bendy and does not retain its shape well. But if you do not want a firm toy you should probably choose something else.

Doc Johnson markets that the silicone will warm up to body temperature and it does relatively quickly. I do not notice any difference compared to my other silicone toys, but it is a nice property of silicone. Silicone is a bad conductor of heat though, so this toy will not work if you want to cool it down. It will stay cool for only a very short time. Something like stainless steel would be far better for temperature play.

The toy does have some prominent texture to it. There are three big bumps along the backside of the toy. Each ridge is fairly pronounced and they can be felt when the toy is inserted. If you have never experimented with texture I might suggest a smaller toy to begin with.

You can insert this toy with the bumps facing the prostate or with the smooth side facing the prostate. Both jut give different experiences.

    • Not porous at all

Design / Shape / Size

The Big Man is designed to be three butt plugs in one. Each ridge represents a different "size" of plug you can insert. I personally do not think it works super well as three butt plugs. It is kind of weird to have most of the plug hanging out. Gravity takes over and it falls out if you are standing up. But if you are sitting/lying down it could work as three "step" or three "sizes"

The Dimensions of the toy are as follows:

Length: 5 1/2"
Insertable length: 4 3/4"
Circumference: 7"
Diameter: 2 1/4"
Weight: 0.3 lb

This is a very large butt plug. At its largest point it has a diameter of 2.25 inches. I would also like to point out the difference between 1.5 and 1.75 is smaller than the difference between 2.0 and 2.25. Diameter = pi times radius squared. So basically you are increasing size exponentially as you increase diameter. For those of you that hate math. Basically as you move up sizes in butt plug the size increase is bigger than the last one. So be careful when moving up steps. You do not want to jump size too much, or else you will end up with a toy you cannot fit/use. Again I would like to reiterate this is an advanced user toy. It is huge and I would recommend having using a 2.0 diameter toy before thinking about trying this one.

The shape of the toy makes sense. I think it is designed to have the smooth side go towards the prostate, but you can use the pointy ridges towards the prostate for an interesting sensation.

This toy is good for travel. Silicone is very durable and is not going to shatter or anything. It would be fine to throw this in a suitcase and forget about it. This toy is quite large and I would not consider it discreet.

    • Partner play


This toy is something you sit down and have a nice romantic evening with. It is not something you are going to insert right away. You are going to need lots of lube, and lots of time. You will need to first start off with your fingers and warm up your bum. Then start with a beginner toy, then an intermediate toy, then finally slowly play with this toy until you insert it. A toy this big takes time. But it can be worth it. When you have something this large in your bum you are going to have intense stimulation. You are filled with a large filling sensation and with that much pressure on your prostate it feels like you are continuously ejaculating. It feels like a small orgasm that just keeps on going and going and going until you remove this toy.

For female butt plugs can place pressure on the vagina walls. This can create some tightness, so when a penis or a toy is inserted a more intense feeling is achieved. Being a male I cannot personally comment on it, but with a toy this large I think it is going to change the way penetration feels.

The toy tapers down to a small ending that allows your sphincter muscles to relax once the humungous bulb has been inserted. It has a large round end after that to prevent the toy from getting stuck. Round bases do not make much sense to me. Your butt crack is not round. It is a horizontal line. I think a rectangular base makes more sense. But since this is not a good long term toy I do not think it is a huge issue. If you were wearing this toy for half a day it could become uncomfortable, but I think most people will only use this toy for half an hour or an hour.

Overall if you are looking for a large toy this is going to perform great. It is large and in charge and is going to provide you with all the stimulation you could want.

Care and Maintenance

Because this toy is made out of food grade silicone it is very easy to maintain. After every use I wash mine with warm water and anti-bacterial soap and it stays very clean. If you are going to switch partners with it you can also sterilize it either with a 10% bleach solution, boil it for three minutes, or stick it in the dishwasher on the top rack with no soap.

Silicone toys are best to store away from each other. They can actually damage each other if they touch each other. This is fairly uncommon, but I think it is still a good practice to store them separately. I just use Ziploc bags to store them.

This toy is made of silicone and therefore should not be used with a silicone based lube. It should only be used with a water or an oil based lube. (oil based lube is bad vaginally, but can be used anally).

The toy can collect dust, so a quick rinse before use is never a bad idea, but I think that holds true with just about every toy.
    • Easy to clean
    • Easy to store


This toy is packed in a basic plastic shell. You can see the butt plug through it, because it is a clear plastic. I would not consider the packaging clear at all, because you can clearly see the toy, and well it looks like a butt plug. It is possible to store this toy in the packaging, but I did not. The packaging is quite large and I would rather store this toy in a Ziploc bag in my toy box.

Here is a photo of the front of the toy packaging

Here is a photo of the back of the toy packaging

There are no instructions that come with the toy, but it is pretty self explanatory. The plastic packaging is recyclable.

    • Not discreet

Personal comments

As a fan of BDSM I think this toy can be used as punishment. You can punish your submissive by making them take this toy in their ass. Anal training is commonly used within the BDSM scene.

You can also make your submissive keep this toy in as long as possible. With a toy this large it can be hard to keep it in without ever adjusting. So you can make a "test" by inserting the toy, restraining his or her hands and seeing how long they can keep the toy in.
