Girth Game Level-Up: SuperFit XL Dilator Review & How-To
For when “Oh noooo, is it going to fit?” isn't just teasing dirty talk.

If you're feeling intimidation with penetration, you have options, including dilator kits. Think of these sets as the no-frill form of dildos, with gradually increasing size increments, made for a mission of comfortable expansion and relaxation.
They come in a diverse range of diameters — VWELL silicone dilators range from “a bit wider than a pencil or AAA battery” to “about an average cock” to “the width of a tall slim 12 oz energy drink can.”
So if warming up to any penetration is your goal, there's a dilator size for you, and the how-to section of this post can help.
If you're specifically leveling up your girth game — maybe you:
- Had a hard time with a well-endowed partner
- Were intimidated by a big dick
- Simply want to enjoy bigger penises or toys…

…the VWELL SuperFit XL dilator kit helps you do exactly that. It goes well beyond the standard stretching set, so you can confidently consume cocks of just about any size.

First Impression: Serious Size Training
(These aren't your standard medical dilators!)
Sometimes, I watch myself in the mirror using a fat dildo and think, however fleetingly, “How does that fit inside her?”
I had a similar feeling when hefting the VWELL Superfit XL dilators for the first time. They're not fucking around; not only are they thick, but they're also firm and formidable, even for those with a penchant for penetration. (The 2.3” wide one is no joke.)
The good news is that there's a lot to work with in terms of the next step up.
The bad news is that the increments between each step aren't exactly gentle.

Even the first silicone dilator in the Superfit XL kit can be a lot. At these sizes and this firmness, the ideal user:
- Is already very comfortable with penetration with an average-sized cock
- Enjoys when an insertable is damn near rock-hard
- Really knows what they want — to be stuffed the fuck up
- Prioritizes penetrative pleasure enough to take their time
If you're not quite there yet, be sure to check the verdict section for gentler alternatives, and consider consulting a pelvic floor physiotherapist or gynecologist if the discomfort persists.
Whichever toys for vaginal stretching you choose, here are my straight up penetration pro tips.
They're not fucking around; not only are they thick, but they're also firm and formidable, even for those with a penchant for penetration.
How to Use Your Dilator Kit to Train for Big Dick
Consider this section the condensed version of my guide to huge dildos and fisting.

For now, let's focus on tips for safe vaginal stretching with a large dilator set.
Go slower than you think you need to. I'm talking not even a millimeter per second.
Penetration Preparation: Getting Your Body Ready
- Take time to relax before even touching your toys — consider hip opening stretches like happy baby, pigeon pose, or deep squats.
- Apply abundant water-based lube!
- Breathe deep, letting your belly expand like a balloon, relaxing with every inhale.
- OPTIONAL: Use a massager on the outside, if it helps you relax, before and during penetration.
Active Training: Working With Your Dilators
ESSENTIAL INSTRUCTIONS
- Alternate between steady pressure and gentle movement with the dilator.
- Hold the dilator in place at the entrance and go slower than you think you need to. I'm talking not even a millimeter per second.
- Turning the vibrations on when using the first dilator in the kit can help, too.
- Start with small circles, slow rotation, swiveling motions, or sort thrusts when you're ready.
- Relax when you inhale and contract just a little when you exhale — you don't necessarily have to do a hard squeeze, but get comfortable with the dilator's presence.
- Push the dilator in on the inhale — and, of course, pause when you encounter tension.
- Repeat with the next size up, if you're comfortable with it.

EXTRA SUPPORT
- Consider keeping the external vibrations going. A bullet vibrator, slender G‑spot vibrator, or mini-wand can help here.
- Place more pressure on the back wall, if that's comfortable for you, so there's less friction near the urethra.
- If visualization helps, and you're lying on your back, it might help to imagine and repeat, “My back wall is heavy” as your pelvic floor relaxes.
Aftercare: Post-Training Recovery
- If you feel general soreness in the area after, back off and give your body a break
- When in doubt, ask a pelvic floor therapist for help.
- You might also feel minor pain points flaring up; consider pairing your progressive dilation time with a focused trigger release wand
- Kiwi by the Pelvic People is lovely for shallow penetration and use on the outside
- The Intimate Rose can go deeper and is more precise
- Stretch the muscles in the surrounding area; consider butterfly stretches, figure 4, dragon pose, and so on.
- One great resource, among many, for pelvic floor-nourishing stretches is Heal Pelvic Pain by Amy Stein.
The silicone firmness was a lot to handle — it hurt sooooo goood — but I came so hard.

My Experience With the VWELL SuperFit XL Kit
I'm quickly on the plateau and if I even so much as think extra spicy thoughts, I'm shaking and clenching again… and cumming again because of that and getting overwhelmed by the sensation again and cumming again…
The size training how-to above isn't just lip service; I had to take my time and breathe deep, nudging at the entrance. (Cue flashback to all the times I've heard, “You are tight” upon initial insertion.)
I do warm up and relax easily, but it takes time.
Even the first dilator in this kit was a lot, since it's so rigid. I clench and cum on its unyielding pressure when tip drilling. The vibrations — 3 steady settings and 7 patterns — are buzzy but welcome.
And once it's all the way in, I find myself at times pulling it in with my contractions.

I love clenching around it when I cum, and even more so with the second dilator, combining deep breathing with (hard) squeezing and replaying scenes and daydreams.
Orgasms via breathing and clenching are a common occurrence for me (thanks, Barbara Carrellas!), but having something girthy inside me takes it to the next level. I'm quickly on the plateau and if I even so much as think extra spicy thoughts, I'm shaking and clenching again……….. and cumming again because of that and getting overwhelmed by the sensation again and cumming again …………..
That's not to say that you will have huge orgasms on these huge dilators. Every body is a bit different. However, trying more girth and clenching around it can place more pressure on the internal clitoris for more intense orgasms, if you're into penetration.
(And if you've read this far, you probably are.)
Verdict: Is SuperFit XL Your Next Size Step?
Drooling at the pleasure payoff, but think it might be a challenge? As always, you have options.

Who Should Use Something Else For Size Training?
Skip the SuperFit XL silicone dilator kit if:
- …an average-sized penis or mid-sized dildo already feels like a lot
- …you know you want something squishy
- …you crave focused pressure beyond a big stretch
The firmness means you'll feel a more intense stretch than you might expect — especially if your frame of reference is a cock or a squishy dildo.
If you seek more gentle dilation with something softer or smaller, consider the following toys:
- A different dilator set from VWELL — you have 5‑piece and 10-piece options, including one that starts a bit bigger than a pencil in diameter
- Squishy vaginal plugs, such as:
- Uberrime's Sensi, which is about average diameter, locks in against my walls and ceiling when I squeeze
- SquarePegToys’ G Squeeze, which comes in eight sizes for a delicious range, and has a generous G‑spotty swell
- Dee's Big Daddies silicone dildos, which generally start with an average size (the Dee's Wee Daddies line), come in four larger sizes, and can be made in two firmnesses: squishy and squishier
I wouldn't say the SuperFit XL increments are the most practical for sex with a well-endowed partner — ideally, they'd be softer with smaller spacing in between each step. However, the kit needed to exist, and there are clearly shoppers who crave such a set.

Who Would Love the VWELL SuperFit XL Kit?
The hard silicone and progressive sizing make this large dilator a must-have for those who:
- …are already comfortable with girth but want to maintain elasticity
- …adore something firm to clench around
- …love a challenge
- … are willing to take their time to warm up
- … don't want to spend big bucks on several separate silicone dildos for stretching, and don't care to have any added “frills”
- …otherwise want to enjoy big dick, but it takes some work to get it in
The Superfit XL dilator kit bundles beyond the standard sizes for serious stuffing. It's for those who want to get filled so good. Get straight up stretching for a fair price, from above average to absolutely aAaAaaaaAAAAAA.
