I am often asked by readers to recommend a giant dildo for strap-on sex. Indeed, there is a lot of demand out there for large dildos that are lengthy, girthy, and harness-compatible. The most common giant dildo requests are for at least 7 inches in length and 2 inches in diameter, so I created this guide with these measurements in mind. All of the dildos listed here are non-toxic, phthalate-free, and manufactured by companies whose products I personally use and trust.
Before purchasing a giant dildo, make sure you have a harness that is capable of equipping one as well as appropriately sized O-rings. I personally use the Terra Firma Harness and the Tantus Silicone O-ring Set for large dildos.
Tantus General
- Diameter: 2 inches
- Length: 7 inches
- Perfect curve for prostate stimulation
- Officially recommended for anal play by Tantus
- Head is thinner than the shaft, making it the easiest dildo to insert
Out the large dildo options available, the General is my top giant pegging dildo recommendation. Tantus specifically recommends this dildo for anal play, and you can tell that it was clearly designed for this purpose. The angle of the curve is just right for hitting the prostate and the gentle bumps provide additional stimulation. The silicone material is firm enough so that the dildo remains upright in the harness without flopping or falling under its weight. The head is thinner than the shaft, making the General a bit easier to insert than the rest of the giant dildo options.
While the General may be on the “small” side of my recommendations, its features certainly make it the easiest and most forgiving on the ass. People looking for their first giant anal dildo experience should consider starting with the General first.
Vixen Outlaw
- Diameter: 2 inches
- Length: 8.5 inches
- Lifetime Guarantee
- Made from VixSkin silicone to provide a very realistic feel
- Best combination of length and girth
Overall, the Outlaw is excellent quality dildo that provides the most bulk out of all the other giant dildo options. It gets my top recommendation because it offers the best combination of length and girth in a market where lengthy, girthy, and harness-compatible dildos are rare.
The unusual size, however, isn’t the only reason why the Outlaw is my top pick. The Outlaw is manufactured by Vixen Creations, which is a dildo manufacturer that is well-known for their high-quality products. They use a special non-toxic material for their dildos called VixSkin, which feels like real flesh. The realistic VixSkin material does make the Outlaw a bit softer than your average dildo, but still provides a satisfying amount of firmness and performs well when strapped into a harness.
Vixen Maverick
- Diameter: 2 inches
- Length: 7 inches
- Lifetime Guarantee
- Made from VixSkin silicone to provide a very realistic feel
- Curved for prostate and G-spot stimulation
Although the Outlaw made the top of my list for its enormous size, its “little” brother the Maverick is arguably more compatible for strap-on sex. Unlike the Outlaw, the Maverick is perfectly angled for prostate and G-spot stimulation. The smaller size and friendlier dildo base offers more stability when strapped on than the Outlaw, so thrusting and maneuvering into position are somewhat easier.
Overall, both the Outlaw and Maverick are excellent dildos both in quality and in function. Use the Outlaw for when you want to wow your partner with its gigantic size, and whip out the Maverick for when you need something big, but practical (e.g. for vigorous thrusting or unusual positions).
Vamp Joplin
- Diameter: 2.25 inches
- Length: 8 inches
- Made from Softskin silicone to provide a realistic feel
- Available in a wide variety of gorgeous swirling colors
- If you want the girth but not the length, check out the slightly shorter, but equally girthy Vamp Greta (7″ x 2.25″).
If girth is what you’re looking for, then check out the Joplin. This is the first dildo on my list to have a diameter of over two inches, making the Joplin one of the girthiest dildos on the market (even girthier than the famous Randy). The eight-inch length makes it only a half-inch shorter than the Outlaw. Overall, everything about this dildo is huge!
The Joplin is made from a silicone material that the manufacturer, Vamp, calls Softskin. This material is meant to feel like real flesh and is similar to the VixSkin mentioned in the Outlaw recommendation. It’s a high-quality material that is phthalate-free and non-toxic. While Joplin might feel realistic, though, it certainly doesn’t look realistic. Like all Vamp dildos, it comes in variety of gorgeous swirling colors. The Joplin is as pretty as it is huge.
Vamp Carina
- Diameter: 3 inches
- Length: 9 inches
- Made from Softskin silicone to provide a realistic feel
- Available in a wide variety of gorgeous colors
- If you want the length but not the girth, then check out the slightly thinner Vamp Gianni (9″ x 2″)
- Largest harness-compatible dildo available
I’ve never used the Carina myself, but with that absolutely massive size and that gorgeous color, how could I not mention it? How could I not at least alert my readers to this beautiful giant’s existence? Carina’s got a full two inches on some of these other big dildos, and a “giant dildo guide” is incomplete without it.
Carina is manufactured by the same company as the Joplin, and uses the same Softskin silicone that feels similar to real flesh. The dildo is non-toxic, phthalate-free, and handmade. Like Joplin, Carina is also available in a wide variety of swirling colors.
Honorable Mentions: Other Giant Dildos Worth Checking Out
Here’s a group of large, harness-compatible dildos that have the girth to satisfy a size queen, but not necessarily the length. All dildos listed here are non-toxic, phthalate-free, and manufactured by companies known for their high-quality products. Some of them I’ve used myself, others I’m only listing here for their size. All of them I’d feel comfortable using myself if given the opportunity.
