Read on for the Clone-a-Willy dildo instructions, or check out these bullet points for the TL;DR!

• A Clone-a-Willy kit has everything you need to create a personalised, body-safe dildo. The kit captures every detail of an erect penis using moulding powder and silicone – it's a unique, high-quality toy you can make at home.

• Prep your space and your body before you start. Gathering your tools first, tidying or greasing pubic hair, and finding a wipeable surface to prevent too much mess will make the whole process easier.

• Teamwork makes for a better mould. You’ll need to move through the steps quickly once you get going, so having a partner to help with mixing, positioning, and keeping you hard will be really useful.

• Nail the timing and temperature. Use water at the right warmth, mix quickly and insert your penis promptly – that way, you'll get a clean and detailed mould that looks just like the real thing.

• Allow the clone to fully cure. Letting the mould set for several hours, and the silicone cure for 24 hours, means that your finished dildo will be smooth and durable.

• Enjoy and explore your new toy. Use plenty of water-based lube, and experiment with different angles and sensations – these toys are great for solo or couples play.

• Clean and store it properly. Wash thoroughly before and after use, keep it dry, and store it in its own pouch or box – this will keep your clone in great condition.

Clone-a-Willy is a penis casting kit that allows you to create a life-like, DIY dildo at home. This moulding kit uses body-safe silicone, so your new toy will be the same material as other quality dildos. This silicone comes in a range of shades: we carry light, medium and dark skin tones, and have some glow-in-the-dark varieties too. Cheeky!

People love Clone-a-Willy kits because they turn a sex toy into something personal, playful, and non-threatening; you’re celebrating what’s already in the bedroom, not adding competition. They’re also perfect for long-distance relationships; even when your partner’s away, you can still play together (sort of). All in all, it’s a fun and intimate way to stay connected.

It can even be a playful fantasy booster – “Try a three-way with your partner and a Clone-a-Willy”, says sex and relationships expert Annabelle Knight – or a way to recreate your fave toys with added power. “If you have a favourite dildo that doesn’t vibrate, you might want that exact shape but in vibrator form: you can, with Clone-a-Willy.”

You’ll find a moulding tube, algae-based moulding powder, a two-part platinum-cure silicone mix, a single-speed vibrating unit (like a bullet vibe!), a thermometer, a stirring stick and step-by-step instructions.

As well as everything included in the kit, you’ll want to have these bits to hand:

• measuring cup

• spatula

• disposable container

• mixing bowl

• pair of scissors or craft knife

• square of cardboard, measuring 4”x4” inches

• pen

• Timer

• old towel

“You’ll need everything that comes with this kit, so don’t chuck anything away,” says Annabelle. “Read the instructions on the outer packaging, and make sure you know what you’re doing before you get cloning!”

It can be tricky to get the process perfect first time, so don’t rush it. Some of our customers even recommend reading the instructions twice before you get started, and also tackling the moulding process as a pair.

Doing everything on your own will be fiddly; you’ll see why in our step-by-step guide below, so team up with your partner to create the toy together. Keep it light and try to laugh off any mishaps – it’s just like going on a crafting date, but sexier!

H3 Trim first

“If you’ve got pubic hair and don’t want to shave it, use a bit of Vaseline just to grease the wheel, so to speak!” says Annabelle. “So that when you remove the tube, you’re not giving yourself a wax at the same time.” Otherwise, you can give the area a quick tidy-up before moulding. It doesn’t need to be a full landscaping job – just enough to avoid any stray hairs getting caught in the silicone.

Find a splash zone

The moulding mix is naturally runny at first, and some of it will spill over the sides of the tube once you get round to inserting your hard-on later in the process. So set up your old towel on the floor somewhere tiled and wipeable, just in case there’s any overspill. Once the mixture sets, it peels off hard surfaces with zero fuss; you just want to avoid carpets and bedding.

Prepare your moulding tube

Place the tube next to your erect penis with the open end pointing away from you. Mark a half-inch beyond the tip of your penis with your pen and cut off the open end at this mark.

“After you’ve cut the tube, if you cut it at an angle it fits against your body better,” says Annabelle. “Then if you put some masking tape or duct tape around the edge, it softens it so you don’t get any nicks or cuts.”

At this point, it’s a good idea for the person with the penis being cloned to get hard. If that’s you, let your lover take over with the next few steps so you can stroke your penis to full size, ready to be cloned in all its glory!

Accommodate any curves

If your penis curves, tilt the tube to match the angle of your erection as you insert yourself. This helps capture a realistic shape and prevents the penis from pressing unevenly against the mould walls.

Prepare the moulding mixture

Measure 1¾ cups of 90°F / 32°C water from the tap (avoid microwaving – this’ll make it too hot). Pour the water into your mixing bowl. Cut open the bag of moulding powder, add it to the water and start your timer; mix for 45 seconds. It’s fine if the mixture still looks a bit lumpy by the end.

A lot of people in the reviews recommend making the water temperature slightly higher than recommended by Clone-a-Willy. This way, the water will cool down to the correct temperature by the time everything goes into the mixing bowl.

Slide into the tube

Quickly pour all of the mixture into the plastic tube. While you’re standing on your old towel, insert your erection fully into the tube as fast as possible. Hold the tube against your body for one to two minutes until the silicone begins to set.

Keep your erection hard

Maintaining a boner long enough for the gel to set can be surprisingly tricky, even for people who never go soft during sex. “Try anything you can to help maintain your erection,” says Annabelle. “Porn in the background, sexy dance from your partner, nipple play…”

Some people find that wearing a cock ring can help them stay hard, as rings restrict blood flow away from your penis. If you’re happy to have a cock-ring shape on your toy, you could use one at the base of your penis – or you could use one that goes around your balls, if you’d rather not have one on your toy. Only try this if you’re confident that cock rings help you stay erect (you can always practice first!).

Leave the mould to set

Once you feel the gel has fully solidified, gently remove your penis. Leave the mould to set for four to eight hours; that way, all the details on your clone can develop properly.

Cut the carboard

Cut an “X” into the centre of your cardboard square using your scissors or craft knife – just large enough for the vibrator to push through while still holding it firmly at the screw-on base.

Prepare the silicone mixtures

Mix the two pots of silicone together in your disposable container using the stirring stick. Scrape every bit out of each pot to make sure you’ve got an even blend.

Pour silicone into your mould

Pour out any water that’s collected at the bottom of your mould. Then carefully pour in the silicone mixture. Go slowly to avoid creating air bubbles in your toy.

Insert the vibrator

The vibrator’s screw-top bottom should be held clear of the silicone by the cardboard square at the top of the tube, while the rest of the vibe is inserted down into the silicone. Make sure the mould stays upright, and that you push the vibrator straight into the centre. This’ll mean it won’t sit unevenly inside your toy once it’s finished.

Wait 24 hours

Let the silicone cure for 24 hours. Now’s the perfect time to think about how you’re going to use your new dildo once it’s ready… (Read on for our tips on this!)

Once those 24 hours are up, remove the cardboard and gently pull your brand-new toy out of the mould. Trim away any excess silicone from the base with scissors if you need to. Unscrew the vibrator’s base and pop in an AA battery, then you’re ready to go!

Annabelle gives us her best tips on making the most of your brand-new toy…

Take your time getting aroused

“If you’re using a dildo for the first time, whether alone or with a partner, it’s a good idea to get aroused before you begin to play,” she says. This will help penetration feel pleasurable, as your body will be more relaxed. “Many people like to watch or read erotica or use their hands to stimulate themselves first.”

Use water-based lube

Always use water-based lubricant with your new toy, because silicone lube will deteriorate the material over time. And why use lube generally? It reduces friction between you and your toy, making every clench and thrust feel even more sensual and intense.

Start slowly and gently

“Once you’re fully aroused, you can then begin to insert the tip of the dildo into the vagina [or anus].” Take your time and go at a pace that feels good to you. If you want to stop and hold the toy inside you for a minute while you get used to the sensation, do that! Try touching other erogenous zones while you feel its girth inside you.

Experiment with your toy

“Different people like to use dildos in different ways; the choice is yours.” Why not try:

• Stimulating your clitoris or penis while inserting the dildo into your anus or vulva

• Pairing dildo penetration with oral sex from your lover

• Grinding, thrusting or holding the dildo still beneath you while rocking your hips

In a long-distance sitch or heading off for a business trip? Try using the toy during phone sex with your partner. Remember to tell them how good their penis feels even when you’re apart – that's the beauty of playing with your Clone-a-Willy dildo!

Keep things hygienic

“Whatever you do, you need to remember to clean your dildo before and after each use – just to help prevent nasty infections,” says Annabelle. Soap and warm water or a sex toy cleaner both work well. (Check out our guide on how to clean sex toys for extra tips.)

Store it safely

“When it comes to storage, it’s a good idea to store your dildo in a bag or box to keep it safe, clean, and away from prying eyes.” Keep it in a cool, dry place and make sure it isn’t directly touching any other sex toys.
