Our Review and Rating Procedure

Here at Bedbible, we feel it’s important to give every sex toy an equal footing, no matter its brand name or toy type. To do this, we first conduct extensive research on every product (using personal experience, manufacturer information, and customer feedback) and then use what we’ve learned to rate a product using our standardized rating system! This system is referred to as the “Bedbible Rating” system! By assessing each product’s design, ease of use, and quality, we can highlight a toy’s strengths, bring attention to its weaknesses, and provide its overall sense of value. Of course, second opinions matter, so we share the average user experience (calculated from various customer reviews) in the form of the “User Ratings” score as well!

Our Review and Rating Procedure

Types of Large Strap-On 

First things first: you’ll need to decide which type of large strap-on you want! There are a few different options to choose from, including:

  • Dildo & Harness Kits – These kits include both a dildo and a harness, making them perfect for pegging beginners who have the drive, but lack the proper equipment! Available with both standard and plus-sized strap on harnesses, you’ll want to pay close attention to all applicable sizes when buying a complete kit to ensure that everything fits properly.
  • Standalone Dildos – If you already have a harness, then you might just need a new dildo to take things to the next level! Most dildos with flared bases can be used with a strap-on harness, giving you a nearly unlimited number of options to choose from. Bored with just one shaft? Pick yourself up a double penetration model instead!
  • Hollow Strap-Ons – These hollow toys are great because they can be worn by both men and women! Whereas women can use them like traditional strap-on dildos, men with either hard OR flaccid penises can use them to please their partners. This makes them invaluable for men who suffer from ED.
  • Strapless Strap-ons – Designed to fit into & be held by the vagina, these toys allow both partners to share in the fun! Features vary by model, but many offer vibration functions for the female partner to enjoy while penetrating her partner!

 

What to Look for When Buying a Large Strap-On

Now that you’ve decided what type of large strap-on you want, you’ll need to check the specifications of any potential contender to make sure that the particular toy can check off all your boxes. Here are a few things to look for when buying a large strap-on!

  • Harness Size – People come in all different shapes and sizes. Regardless of your size, you’ll need to make sure that your choice of harness will fit properly! Fortunately, manufacturers make adjustable harnesses so the sizing doesn’t have to be exact. There are also plus-size harnesses available for people who have a bit more to love!
  • Harness Design – Most strap-on harnesses assume you don’t have a penis. In many cases, that may be accurate but it’s not a universal truth: men can wear strap-ons too! Options vary, with some models allowing a person to harness both a dildo and their penis separately, and others placing the penis inside of the strap-on dildo for erection-full (or erection-less!) penetration.
  • Dildo Size – How big of a dildo is your partner looking for? You’ll want to discuss length and width (girth) parameters with them before settling on a specific toy.
  • Dildo Realism – Some people value visual realism, whereas others are satisfied with a real feel strap on dildo. Of course, you can have both if you wish! There are many different dildos on the market today, so as long as your budget can accommodate it, the dildo of your dreams is most likely just a few clicks away.
  • Extra Features – When a standard strap-on dildo isn’t enough, up the ante with extra features! Although large strap-ons don’t have quite as many variants as other types of toys, there are still vibrating and even ejaculating models for you to choose from!

FAQ

What is the best material for a large dildo?
The only way to guarantee a dildo is completely body safe is to make sure it is made of a non-porous material such as silicone, glass, or metal. PVC and other plastics are often used in cheaper sex toys, so your best bet is to wear a condom over those to prevent bacteria from building up in the toy.
What sort of lube should I use for my large strap-on?
First of all - use lots of it. Use more than you think is necessary. It will be necessary. Second, Silicone lube will slowly degrade the quality of silicone toys, so it's best to use water-based lube for those. Other than that, most materials will be safe to us with silicone lube — the benefit is it tends to last much longer! It's just tricker to wash out.
How often should I clean my large strap-on?
We highly recommend cleaning before and after each use, in order to avoid the transfer of unsafe bacteria. This will also help your toy last longer! You'll also want to clean between switching from vaginal to anal penetration, and the other way around.
Can I use my large strap-on in a harness?
As long as it fits - yes! You'll want to look for harness-compatible toys, and check the diameter of your O-ring before you purchase, however. It goes without saying that larger dildos will probably have larger bases/diameters, but it can be easy to forget.
Can I use a large strap-on anally?
Yes. HOWEVER. There's nothing stopping the dildo from going ALL the way up there, unlike with a vagina - so you'll want to be careful choosing the size and ENSURE the dildo has a flared base, or it's liable to get lost inside you. You may have heard of the Italian man who had to have a 23-inch dildo removed from his anus at the hospital. Do not be that man.

What is a large dildo?

A large strap-on is exactly what it says on the tin! A large strap-on is just a dildo that stands out for being bigger than the rest. A dildo is a phallic sex toy designed for penetrative play that can be used in a number of ways. Primarily, it is used to simulate a penis for blowjobs, anal penetration, vaginal penetration, you name it! It can also be used as simply a tool to reach G-spot or p-spot orgasm. Large strap-ons can be made from both porous and non-porous materials, but you should always opt for a non-porous toy if possible. Although many strap-ons are just penis-shaped sex toys, some models offer additional benefits like a hollow shaft (which can accommodate a penis inside) or vibrations.

This hollow strap-on kit from Doc Johnson has it all! For the price, while it is expensive, you get three dildos and a comfortable, compatible harness. It’s a great kit for working up to larger sizes, and the hollow dildos (especially the larger ones) can fit a small bullet vibe or thin vibrator with ease (or a larger one, if there isn’t also a penis in there). They’re firm enough to be used on their own, or as a penis extender for deeper and more satisfying penetration.

Another great kit – the Lovehoney Deluxe Strap-On Harness kit is good for working up to larger sizes. It didn’t quite take the top spot, because the difference between the two dildos is 2.4 inches, so it’s not necessarily the best training kit. It does, however, provide a good beginner dildo if you’re not quite ready for the larger one. Plus, the dildos are equipped with suction cups for hands-free fun, if you’re not using the included harness.

This extra-large hollow dildo from Fetish Fantasy is not for the faint of heart. This 10-inch PVC dildo boasts hyperrealistic details, like pronounced veins for added texture along the shaft, bulbous head for realistic sensations, and sculpted balls for the full effect. At a 2-inch girth, this is absolutely not for beginners, but if you’re searching for that satisfying full feeling, you’re sure to find it here. Note: this material is porous, so use of a non-lubricated condom is highly recommended.

This one is CERTAINLY not for beginners. The Extreme EXTRA-Large Hollow Strap-On from Pipe Dreams has 10 inches (25.4 cm) of insertable length. It’s great if you like that full feeling, and even better if you’re into something with super-realistic details! As with all PVC products, we recommend using a condom (you’ll need a large one!), as PVC is a porous material that can be difficult to clean lingering bacteria from.

It’s worth noting that the suction cup isn’t super effective, so you’ll want to look elsewhere for wall-banging dilo action.

Strap in! These large dildos are harness-compatible.

How Big is Too Big?

If you’re going overboard with size, the impact can be lifelong and not particularly positive. While the body can self-heal, obviously, it does so only to an extent. In some cases, it can’t become brand new. A dildo that’s too long or too wide can cause slight tears in the orifice if you don’t use the right amount of lube. Always get lubricant to go with big dildos.

At the same time, it’s important to consider that the concept of ‘large’ varies depending on the user’s own size. Prior to insertion, you might need to undergo a period of stretching, especially if you’re going to use it anally. Anal stretching can be an extended process because the rectum does not self-lubricate, like the vagina. You can use trainer kits to stretch orifices safely and slowly. These kits begin with a smaller width and size, then add more in small increments.

How to use a large dildo

Please use lube. If there was ever a time, this is the time. Whatever hole you put it in, it’s going to be stretching out, probably more than it’s used to, and lube will help ease the dildo in as comfortably as possible! Water-based lube is recommended for silicone toys, because silicone-based lube will degrade the quality over time.

How to clean your large dildo

Because dildos come in all shapes, sizes, and materials, it's important to check the details for your specific toy before you clean it. Below is a summary of how to clean the most common dildo materials! It is critical to clean your dildo before and after use, to avoid bacteria infiltrating your vagina, anus, or mouth. To clean, you'll need: warm water, sex toy cleaner/antibacterial soap, and a clean, dry towel. If your double dildo is made from a non-porous material (which is most common), it won't absorb bacteria easily, however you still need to clean it thoroughly to ensure you avoid any nasty bacteria entering your system! Non-porous materials include: silicone, borosilicate glass, Lucite, stainless steel etc. Porous materials include: jelly, PVC, vinyl, rubber etc. Cleaning different types of dildos: Vibrator/motorized toys: Never submerge your motorized toys in water! (If battery powered, take the batteries out before cleaning). The easiest way to clean them is to wipe them down using a warm, damp cloth with antibacterial soap. Be sure to either air dry thoroughly, or dry with a towel until bone dry. Non-porous materials/porous materials: If not motorized, feel free to submerge your toy in warm soapy water, and thoroughly dry before storing. For porous materials, bacteria can build up over time in the pores of the toy, which means you should take extra care when cleaning, and ensure the toy is bone dry before storing. Glass/Stainless Steel: You can safely boil your borosilicate glass, and stainless steel toy to sterilize them; borosilicate glass is highly resistant to thermal shock, meaning it is safe to boil (and this is why it's great for temperature play!). When your toys are clean and thoroughly dry, you should store them safely; find a place where you can store your toy(s) with plenty of room for others, and where they will be kept away from anything like dust or wetness – these will only cause bacteria to develop!

Porous
materials

Soft plastic, hard plastic, jelly, rubber, Cyberskin are all porous materials, meaning that small particles and bacteria can penetrate the surface. This makes it impossible to completely clean these types of materials.

Therefore, it is recommended that you use a condom with these types of toys, especially if you are sharing them. Clean these toys with mild soapy water and dry gently with a towel. These materials are more easily damaged, so be sure to be gentle and make sure your toys are completely dry before storing.

Non-propous
materials

Silicone, glass, stainless steel and some hard plastics can all be washed using a mild soap (like you would use on your body) and warm water. Just be careful if your toy contains electrical parts.

Silicone and stainless steel toys without any electrical parts can also be boiled for sterilisation.

The toys with electrical
components

If your toys contain electrical components, be extra careful when cleaning them and always check the instructions provided with the toy. You can use a gentle cloth and soap to wipe or sex toy cleaner or cleaning wipe to down your toy, making sure that no water comes into contact with the electrical parts.
