Quick answer
Choose a soft dildo if comfort matters most. Soft toys are more forgiving when you're new, sensitive or using a larger size. Choose a firm dildo if you want focused pressure on the G-spot or prostate, or a toy that holds its shape in a harness. Dual-density dildos have a soft outer layer over a firmer core and are the best compromise for most people. Firmness matters less than size, though, so check the diameter before anything else.
Choose a soft dildo if comfort matters most: it’s more forgiving when you’re new, sensitive or trying a larger size. Choose a firm dildo for focused pressure on the G-spot or prostate, or for a toy that holds its shape in a harness. Dual-density toys, with a soft outer layer over a firmer core, are the best compromise for most people. Whatever you choose, check the diameter first. Firmness changes how a toy feels, but width decides whether it’s comfortable.
What dildo firmness means
Firmness is how much a toy bends or compresses when you squeeze or insert it. It depends on the material and on how the toy is built:
- Soft: squishy surface and a flexible body that bends with you.
- Firm: dense material with little or no give. Glass and steel are the extreme.
- Dual-density: a soft outer layer over a firmer core.
Retailers rarely give a firmness number, so you’ll usually be going by descriptions like “ultra-soft”, “flexible” or “dual-density”. Treat them as rough guides.
Soft dildos
Good for: beginners, sensitive users, larger sizes, longer sessions and warm-up play.
Soft toys cushion each movement and adapt to your body’s curves, so they’re more comfortable to insert and less likely to press uncomfortably. The trade-off is less precise pressure and, with very soft toys, a tendency to bend when used in a harness.
Example: ultra-soft, flexible thrusting dildo
Neil Ultra-Soft & Flexible Thrusting Dildo, Easy Insertion, Gentle Yet Satisfy
Best for Buyers who find firm dildos uncomfortable but want some girth.
A soft, flexible thrusting dildo with a wider diameter, for people who prefer a squishy feel.
- Soft, flexible silicone
- About 6.7 in insertable
- Remote control
- Thrust travel
- 0.78 in Manufacturer-stated
- Diameter
- 1.77 in Manufacturer-stated
- Material
- Silicone Retailer listing
- Diameter
- 1.77 in Retailer listing
- Insertable length
- 6.69 in Retailer listing
At about 1.77 in wide, this is soft but not small. Softness doesn’t make a wide toy beginner-sized.
Firm dildos
Good for: G-spot and prostate pressure, harness play, and people who like a filling, solid feel.
A firm toy doesn’t deflect, so every movement translates into direct pressure. That makes it easier to target a spot and to control in a harness or on a suction cup. It can feel too intense if you’re tense, new or using a large size.
This budget silicone dildo is described as “soft yet still firm” and has a suction cup for hands-free use, but at about 2.16 in wide it’s a large toy:

Dual-density: the middle ground
Dual-density toys pair a soft outer layer with a firmer core. They feel realistic on the surface, hold their shape for thrusting or harness use, and suit most people who aren’t sure which they prefer.
Example: dual-density vibrating dildo

How size and firmness interact
| Slim (under ~1.4 in) | Medium (~1.4–1.8 in) | Wide (over ~1.8 in) | |
|---|---|---|---|
| Soft | Gentlest option | Comfortable step up | Easier than a firm toy of the same size |
| Firm | Fine for targeted pressure | Intense; build up to it | For experienced users |
Larger, flexible toys are a popular way to go bigger without the full intensity of a firm toy:

How to choose
- New or sensitive? Start soft or dual-density, and slim.
- Want G-spot or prostate pressure? Firm or dual-density, with a curved tip.
- Using a harness? Firm or dual-density with a flared base. See our Fetish Fantasy hollow strap-on review for harness alternatives.
- Going bigger? A softer material makes a larger size easier.
- Want movement? Thrusting dildos add motion. See best thrusting dildos under $100 and thrusting vs vibrating dildos.
Material matters too
Silicone comes in every firmness and is non-porous, so it’s the safest choice at any softness. Very soft TPE, PVC and jelly toys are porous and wear out faster. See toy materials explained.
Care tips for any firmness
- Wash with warm water and mild, unscented soap before and after use.
- Use water-based lube; patch-test silicone lube on silicone toys.
- Store away from heat and sunlight, and keep porous toys apart from others.
- Check soft toys regularly for tears or tackiness.

Frequently asked questions
Are soft dildos better for beginners?
Usually. A softer toy gives a little as you insert it, which is more forgiving while you learn what's comfortable. Size matters more, though. A slim firm toy can be easier than a wide soft one.
Are firm dildos better for G-spot or prostate stimulation?
Many people find them so. A firm, curved toy doesn't bend away from pressure, so it delivers more focused contact. Others find that too intense and prefer a dual-density toy.
What is a dual-density dildo?
A toy with a softer outer layer over a firmer inner core, usually both silicone. It feels squishy on the surface but holds its shape, which suits harness use and realistic feel.
Which firmness is best for a strap-on harness?
Firm or dual-density. Very soft dildos can bend or fold during thrusting, which is frustrating for both partners. A flared base that fits the harness O-ring matters as much as firmness.
Do soft dildos wear out faster?
Soft silicone lasts well with care. Soft TPE, PVC and jelly toys are porous and degrade faster, so they need replacing sooner.
