Our favorite is The Rabbit Mr. Hankey dildo because it comes in 4 sizes, you can pick the firmness level, and the whole shape is nicely tapered to help with a smooth stretching.

Here’s more on each selection:


The Rabbit By Mr. Hankey

The Rabbit by Mr. Hankey

Our #1 pick

Diameter (girth): 3.2″ – 4.6″ | Size Choices: 4 | Insertable length: 9″ | Material: Platinum Silicone | Color choices: 3 | Softness: Medium Firm / 75% soft | Harness Compatible: Vac-U-Lock | Suction Cup: No (flat base)

This is a short and ultra-wide dildo that has a nice curve and smooth increase for nice opening.

It’s perfect for girth lovers as this dildo is wide but short. Choose a softer option to be able to conquer bigger toys faster.

There are four different size options allowing to really customise the fit to your abilities.

The thing is that this dildo doesn’t have the suction cup, but you can always mix and match Vac-U-Lock hole with a suction cup that fits there.

The soft version gets really soft, but it will make the conquering quite a bit faster.

The favorite thing about this dildo is that it gradually increases in size and has a curve to target the G-spot or P-spot.


Buck Vixskin 

Buck Vixskin

Diameter (girth): 1.75″ | Size Choices: 1| Insertable length: 6″ | Material: Platinum Silicone | Color choices: 3 | Softness: Dual Density | Harness Compatible: Yes | Suction Cup: No (flat base)

While all the other selections are very girthy, this is something a lot more manageable.

Buck is made from dual-density silicone giving ultra-realistic and stretching experience. It even has a nice curve for G-spot stroking.

You should know that Vixen Creations makes the best dildos. Dual density means it has rigid inner course and squishy outer core making it feel like a real penis.

Its flat base gets 1.9″ to the largest point so be careful if you’re taking it anally. As you can tell by size it’s not the thickest toy, but a great warm-up dildo.

Vixen also gives each of their toys a life-time warranty. It’s pricey, but you must have at least one Vixskin toy in your collection.


Mr. Universe 

Mr. Universe

Diameter (girth): 3″ | Size Choices: 1 | Insertable length: 7″ | Material: Platinum Silicone | Color choices: 2 | Softness: Super Soft | Harness Compatible: Yes | Suction Cup: No (flat base)

This stretching dildo has great proportions — big fat head and then even thicker base. People love to go between this and Tex plug. A+ toy for size queens, a nice girthy fella.

It comes in two color choices: red and black. The softness is great for this product.

If you’re curious how it could feel – hold your palm out and press on it – that’s how squishy this dildo is.

For pro stretching enthusiasts this is a go-to dildo for stretching. You might need to have a warmup toy for this as it starts pretty wide despite it’s tapered tip.


 Tex Anal Plug 

Tex Anal Plug

Diameter (girth): 3″ | Size Choices: 1 | Insertable length: 4.5″ | Material: Platinum Silicone | Color choices: 1 | Softness: Soft | Harness Compatible: No | Suction Cup: No (flat base)

This is an enormous 3″ girth plug for advanced users. If you’ve been looking to make a gaping reality, this is one way to do it.

Unfortunately, it’s rounded base doesn’t make for good long-term wear, look for SquarePeg T-base egg plug for that.

It’s not as soft as Mr. Universe, but still some pros wear this as butt plug and keep it 1-2 hours in at a time.

It’s thick and will require serious wiggling and shifting and even then you might manage to take in only a couple of times.

But hey, you gotta have goals, huh?

Tex shape makes it stay put in place after you manage that wide opening tip, but I would still be careful with the base.


Rivetor Split Peaches 

Rivetor Split Peaches

Diameter (girth): 3.34″ | Size Choices: 1 | Insertable length: 10″ | Material: Platinum Silicone | Color choices: 3 | Softness: Medium Firm | Harness Compatible: Yes | Suction Cup: No (flat base)

This big dildo is both long and girthy, but it’s great that the tip is tapered to get you started easier.

It has a bit of a curve for G-spot targeting and those bumps add an interesting touch (but maybe too intense for some).

And it’s heavy. It weighs almost 3 lbs and will be a serious showpiece of your collection.

While it doesnt have a suction cup, it does have a wide flat base that stays put securely.

Rivetor will be better for size freaks who like thrusting. Compared to short thick plugs, this is a long and thick dildo with bumps.

The tapered tip allows for easy insertion, but after that it stays that girthy diameter.

If you crave intense sensations and want something completely new, you’ll like this toy.

Here’s a video review (not great quality) explaining more about this dildo.


You checked all the top quality thick dildos… but you’re not ready just yet to shell $100+ for it?

Not to worry, we got you covered.

Here are the cheapest girthiest dildo options. 

3.1 inch and 3.2 inch girth is nothing to scoff at. 

But keep in mind these are not body safe materials, you cannot 100% disinfect these toys and for sensitive bodies they might create bad reactions.

Many people have enjoyed them and have been fine, but my duty is to warn you:

King Cock Chubby 

King Cock Chubby

Diameter (girth): 3.2″ | Size Choices: 1 | Insertable length: 7″ | Material: Soft Plastic | Color choices: 3 | Softness: Medium Firm | Harness Compatible: Yes | Suction Cup: Yes

This is a truly fat dildo. 3.2″ diameter and a suction cup addition ensure that you’ll have the squat of your life. Chubby is one of the rare dildos that comes with a suction cup.

It’s actually quite long too and 7″ insertable length will make you love every inch of its girth.

Chubby is made by Pipedream and comes in two colors: skin color and black.

Be very careful with the measurements, take a look at the video and compare it with the size of the hand. When we say chubby – it’s truly extremely thick dildo!

You may need to buy 2 another toys to work up to this, but if you’re a greedy size queen, this might be just the level of intimidating thickness you need.


American Bombshell 

American Bombshell

Diameter (girth): 3.1″ | Size Choices: 1 | Insertable length: 5″ | Material: PVC | Color choices: 1 | Softness: Medium Firm | Harness Compatible: Vac-U-Lock | Suction Cup: No (but can add)

This is a famous butt plug by Doc Johnson even despite its material.

Material is firm and smooth, yet flexible enough. The neck is very thick and will satisfy the seasoned pro though some mention that it’s a bit smaller than they had hoped.

But could be a nice addition to your smaller toy family.

Contrary to the Chubby dildo this can actually be used as a butt plug. It comes with a nice neck and wide flat base.

But don’t be fooled – eventhough the tip is tapered, it still gets to 3.1″ diameter.

If you can manage it, the neck will keep it in place for extended wear and intense stretching – its surprisingly comfy.

What You Should Consider When Shopping for Huge Girth Dildos?

First of all – avoid eyes bigger than the hole dilemma.

It’s great that you’re aspiring for bigger toys, but if you’ll get a dildo that’s too girthy, it may take your MONTHS till you can comfortably start stretching to that toy.

That’s why it’s important to measure twice, check videos, and really prepare your expectations with the reality.

Remember to size up in 0.25″ increments:

  • 2-inch girth is already pretty challenging.
  • 2–3 inches is where most stretching enthusiasts lie
  • 3–4 inches is the widest that any human can possibly take, and it will take A LOT of work (think:months).

What really helps is that if the dildo slowly increases in thickness and if the tip is tapered.

This will allow you to not need many other toys to warm-up with before taking in the girthy toy.

Even then, keep in mind that you should find good stretching butt plugs that you can wear for extended periods of time. It takes time to stretch your ass and the longer you can spend stretching the faster you’ll achieve your thickest goals.

Consider the material

Here’s the dilemma – thick dildos take quite a bit of material, and platinum silicone gets expensive.

You’ll need to decide if you’ll sacrifice the quality and risk with material, or go safe – but have less and smaller toys.

I am required to always recommend go for a body-safe silicone option that’s proven not to create any bad reactions in your body. It’s the best choice.

But I know that some people simply cannot afford to shell that amount for a dildo. Then you should look at soft plastic (that’s the most body safe option) – and be very careful with cleaning and using PVC dildos.

Listen to your body and if anything feels bad, stop using the toy.

Look for a dildo with a wide base

If you’re using the toy anally, the last thing you want to happen is to have it sucked in your asshole.

These things happen and anus outer sphincter pushes things out, but the inner sphincter pulls things back in. Be wary of this.

A wide, flat base for dildo is a must. If worried, never take the thick dildo in till the base – better be safe than sorry.


How To Stretch & Use Thick Dildos More Effectively?

When you’re stretching it will take a lot of time, lube & careful listening to your body.

Be prepared for it – don’t rush anything, don’t numb your senses.

If you’re new to this – start small!

This is why I included smaller thick dildos in a roster. You’ll need to size up and stretch slowly.

For this you’ll need different thickness dildos to gradually build up to.

Ninja tip: If you’re missing size in between a weird trick is to put a sock or two on the dildo, and then pull a condom over it. It will be perfect for increasing the girth and get to that next stretching size.

Its also important that you get good butt plugs you can wear for a long-time. If you’re serious about reaching your stretching goals, you’ll need to get in the hours of stretching.

Wearing a butt plug is the easiest way to get them. Playing with dildos is fun, but how long can do it right?


Bringing It All Together

That’s it! Have fun, stay safe and I wish you all the success to your widest stretching goals!

If you can take in the Rabbit dildo or Mr. Chubby you can consider yourself a true thick dildo connoisseur and that’s something only 1% can do!

Congratulations on taking the thickest dildo!
