Compare 6-inch and 8-inch silicone dildos on insertable length, girth, suction base, and harness fit. Use clear decision rules to pick your first silicone dildo.
Quick answer
Choose a 6-inch silicone dildo if you want easier insertion, lighter weight, and confident harness play; choose an 8-inch model only when you already enjoy deeper or fuller stimulation and have checked the insertable length, not just the total size.
Total length vs insertable length: the number that matters
A dildo listed as 6 inches may offer only about 5.25 inches of insertable length once the base and curve are accounted for. That difference matters when you are comparing against your own comfort limit. Before buying, look for an insertable measurement; if the listing gives only total length, treat it as an upper bound and size down for a first purchase.
Girth changes the experience as much as length. A shorter dildo with a thick shaft can feel fuller than a longer, slimmer one. The 6-inch Avant Pride P1 lists a 1.4-inch width, while the 8-inch Suga' Daddy is described as an extra-thick, twisted shaft. If you are new to penetration, width is often the more important number to check first.
Suction base and harness compatibility change with size
Both the Avant Pride P1 and the Suga' Daddy use a flared suction cup base. A suction base lets you use the dildo hands-free on a smooth surface, and a flared base also makes the toy harness-compatible in many cases. The Avant Pride P1 is explicitly listed as harness-compatible; the Suga' Daddy has a flared suction cup base, but harness compatibility is not stated in the supplied catalog facts, so verify before relying on it for strap-on play.
Larger dildos put more leverage on a suction cup. An 8-inch, thicker toy may hold less securely on a vertical surface than a lighter 6-inch model, especially during vigorous movement. If hands-free use is a priority, start with the smaller, lighter option and test the suction on a clean, non-porous surface.
Material and care: platinum-cured silicone vs silicone
The Avant Pride P1 is made of body-safe, platinum-cured silicone and is described as non-porous, boilable, and easy to clean. The Suga' Daddy is listed as silicone but does not specify platinum curing or boilability in the supplied facts. Both are silicone, which is a good choice for body safety, but if you want to boil-clean or share the toy after a thorough clean, the Avant Pride P1 gives you that explicit option.
Silicone warms with body heat or warm water, which can make either toy feel more comfortable during use. Avoid silicone-based lubricants with silicone toys unless the manufacturer states otherwise, because they can degrade the surface.
Decision rules for choosing 6 vs 8 inches
- First silicone dildo: Start with a 6-inch model that lists insertable length, such as the Avant Pride P1 at 5.25 inches insertable. You can always size up later once you know your comfort zone. Check the insertable length, not the total length, before you commit.
- Harness or strap-on use: Choose a dildo explicitly listed as harness-compatible. The Avant Pride P1 meets that rule; the Suga' Daddy's harness compatibility is not stated, so confirm with the store before buying it for a harness.
- Hands-free suction play: A lighter 6-inch dildo is easier to keep stuck to a smooth surface during movement. If you want an 8-inch toy for suction play, test the suction cup on a clean, non-porous surface first and keep the angle shallow. Larger toys create more leverage, so suction hold may be less reliable.
- Depth and fullness preference: If you already know you enjoy deeper or thicker penetration, the 8-inch Suga' Daddy's extra-thick shaft is the better match. If you are unsure, the 6-inch option gives you a clearer starting point.
- Cleaning and sharing: If you want to boil-clean or share the toy after cleaning, choose platinum-cured silicone with explicit boilable care instructions, like the Avant Pride P1. The Suga' Daddy is silicone but does not state boilability.
Product facts
- Suga' Daddy 8" Silicone Dildo in Blue: 8-inch silicone dildo with an extra-thick, twisted shaft and a flared suction cup base. The thicker shaft and longer length suit users who already want a fuller, deeper sensation, but the lack of a stated insertable length means you should measure before buying.
Suga' Daddy 8" Silicone Dildo in Blue - Avant Pride P1- 6" Pride Dildo: 6-inch dildo with 5.25 inches insertable, 1.4-inch width, platinum-cured silicone, and a harness-compatible suction cup base. The clear insertable measurement and moderate width make it easier to judge fit, and the harness compatibility adds strap-on versatility.
