Diameter (Girth):
2.4″
Material:
Skin safe rubber
Color Choices:
2
Softness Choices:
Medium firm
Harness Compatible:
Yes
Suction Cup:
Yes

It’s made from Doc Johnson Sil-A-Gel material, but it’s still rubber which is porous.

Some complain that the texture is abrasive and has an odd smell, but again the price and the size (13.5 inches insertable) are unmatchable.

Doc Johnson also makes a popular John Holmes 12 inches big dildo, but again it’s made from PVC material. That’s bad.


How To Pick The Best Huge Dildo For You?

Here’s what you should look out for when picking the perfect one for you:

  • Look out for Size Choices — some huge dildos like Mr.Hankey or King Cock have many lengths and girth variations. In the chart, I’ve indicated the sizes of the largest dildo. Visit the dildo creator site to discover other sizes.
  • Softness Choices some premium toy makers like Tantus and Mr. Hankey indicate the softness level of their big dildos. All big toys are usually squishy and soft, but for some, you can choose the firmness. If in doubt, go for softer. Sometimes you can also write to toy creators and request a custom choice. Keep that in mind.
  • Look for suction base & harness compatibility — depending on how you plan to use your dildo lookout for a base or harness compatibility. Some toys allow adding the Vac-U-Lock hole which can be used for secure use with a harness or adding the suction cup functionality (from Tantus.com).

What You Should Know

These are NOT beginner toys.

These huge dildos are for size freaks and size queens.

They are for extreme stretching and filling experience.

You can get a long dildo and have an enjoyable play because you don’t need to fit 100% of the toy in.

But pick something too wide and you’ll end up with an expensive display sex toy to only look at.

As for the firmness, all huge dildos are soft and squishy. If you’re unsure go for softer.

It helps to think a bit upfront and write down what you’re seeking.

Large silicone dildos take a lot of material and get pricey. 

Mistakes will be costly. So choose wisely.


Quick Tips On How To Use Them

If you’re looking for gigantic toys probably you’re already quite advanced, but still, I feel like it’s our duty to give some advice for safe and enjoyable usage.

A few basics that you must know:

  • there is no such thing as too much lube
  • don’t start with the big toys. make sure you warm-up and stretch with smaller toys. Even more important if you’re going for girth.
  • the more aroused you are the easier and more enjoyable the stretching and filling will be. Use a vibrator on the clit or stroke your penis as you are working the toy.
  • patience is key. It takes a long time to stretch especially the girth anally. You gotta take it slow and listen to your body.
  • relaxation and deep breathing help a ton.

When considering the bigger toy try to go in 0.25 inches diameter sizing up increments. 

Know that vaginally there is a hard limit of 10 inches. This is when you gotta hit the cervix and only childbirth can increase this limit.

Then anally if you go anything deeper than 12 inches make sure to do comprehensive research on the rectum anatomy. 

The deeper you go, the more dangerous the play becomes.


Bringing It All Together
