Homemade Suction Cup Dildo: PRO TIPS from a Sex Toy Tester

We use affiliate links and may receive a small commission on purchases.

Are you here because you would like to create a homemade suction-cup dildo? You’re definitely not the only one, because this seems to be a popular search term. However, we can’t advise trying to DIY this kind of sex toy, especially since it will be used internally and therefore has a much higher bar for safety.

It’s easier than ever to find reliable, high-quality sex toys from reputable retailers at reasonable prices. Check out the Lifelike Lover Classic, which is available for just $35 at Lovehoney. This is an extremely realistic dildo (complete with veins and testicles) on a strong suction-cup base. And, you know that it’s body-friendly and safe to use.

Why You Should Trust Us

My Sex Toy Guide exists to research, review, and report on sex toys and gear. We are staffed by product testers, sex educators, and journalists. Between us, we have dozens of years of professional experience (and even more personal experience) in this industry. You should trust that we know sex toys, and you should also trust that we are an independent publication. We are free to call it like we see it, and we do.

It’s our business to know what’s likely to work and what isn’t. Our loyalty is to our readers, so we are going to tell the truth. And also, because our loyalty is to our readers, we will provide the best information that we have.

What Are Homemade Suction-Cup Dildos?

A suction-cup dildo is a phallic sex toy with a wide base that has a suction cup on the bottom. While you can use a suction-cup dildo the same way that you would use any other dildo, you can also attach the suction-cup base to any smooth surface. If you stick it to a wall, like a shower wall, you can back up to the dildo for rear-entry penetration. And if you stick it to a stable flat surface, you can straddle it and ride to your heart’s content.

In our extensive review of suction-cup dildos, the top contender was the Vixskin Mustang. It had the strongest suction of all the products we tested. The dildo itself is 7.5” in length and gloriously realistic. It is suitable for both anal and vaginal use.

If you don’t want to purchase a suction-cup dildo and instead try to make one at home, then it becomes a DIY suction-cup dildo. Some folks want to attach a suction cup to their favorite dildo, and some want to do the whole thing from scratch. Read on for some ideas and our honest thoughts.

Is Making a DIY Suction-Cup Dildo Safe?

It is not. Any sex toy that is used internally needs to be body-safe. This obviously means the materials (and stuff like medical-grade silicone is not always easy to come by, especially if you only want enough for one sex toy), but it also means seamless construction so there are no nooks and crannies for bacteria or other contaminants to hide. It needs to be able to withstand thorough cleaning.

If you’re going to ride your suction-cup dildo, the suction-cup base has to be strong enough to support your body weight in motion. You do not want it to come off its base while you’re on a downstroke, because that could be very dangerous — at best, it’d be pretty uncomfortable.

Sex toy manufacturers and retailers are invested in creating products that work as expected and are safe when used as expected. That’s why it’s best to buy these products instead of trying to DIY it.

The Best of What’s Out There

If you’ve made it this far, you’re probably still interested in DIYing your own suction-cup dildo. Fair enough! We’ve poked at the darker corners of the internet to bring you suggestions that we think have potential.

Please note that any action that you take based on the information on this website is strictly at your own risk, as laid out in our Terms of Service.

1. Attaching Suction Cup to a Dildo

This project from the r/SexToys forum on Reddit starts out with a professionally produced dildo, which alleviates any concerns about material safety. We recommend trying it standing to test the strength of the suction cups before you try riding it. And even though it’s more work every time you want to play, we advise against storing the dildo with the suction cup attached. Suction cups purchased at a hardware store are not likely to be 100% medical-grade silicone and could degrade the surface of your dildo.

Materials

Dildo with a flat base, and preferably with a firm core
Double-sided suction cups, as strong as you can find
Cleaner for removing adhesive residue (optional, but recommended)

Step-by-Step Guide

Clean the bottom of the dildo base and make sure that it’s completely dry.
Apply the double-sided suction cup to the center of the base of the dildo, and press firmly to ensure a secure attachment.

You may already have a dildo in mind for this project, but if you don’t, we recommend the Vixskin Johnny. It was the highest-rated toy when we reviewed silicone dildos.

2. Building Everything From Scratch

This may be the ultimate DIY suction-cup dildo project because not only are you making it from scratch, but it will be completely unique because it’s an exact copy of your penis (or your partner’s penis). This starts with a Clone-a-Willy kit.

Materials

Clone-a-Willy Kit
Clone-a-Willy Suction Cup attachment
Scissors
Mixing bowl and utensils
Disposable bowl or cup
Square of cardboard
Sex toy cleaner (optional but recommended)

Step-by-Step Guide

Prepare the materials, including making sure that the tube that came with the kit is clean.
Measure your erect penis. Cut the tube down to a size that is about 2” longer than your penis.
Achieve as full an erection as possible (partners can help!). This step is not actually out of order here; the molding gel sets very quickly so you will need to be ready to go as soon as the gel is mixed.
Prepare the molding gel mixture. It’s important to work quickly because the mixture sets in about two minutes. Make sure to maintain your erection during this step.
Pour the mixed molding gel into the tube. Carefully place your erect penis into the mold and make sure that it is centered and fully immersed. You can remove the tube once the alginate has solidified, but it will take about two hours to fully cure.
Mix the silicone in a disposable container and pour it into the mold. Add the vibrator from the kit if desired. Let it sit undisturbed for a full 24 hours.
Carefully remove the Clone-A-Willy dildo from the penis casting and trim any excess silicone from the edges of the mold. Use a wet cloth to wipe it down and remove any residue.
Attach the Clone-a-Willy suction cup to the dildo that you created.

3. Shelf With a Suction-Cup Dildo

This is another project from our trusted friends on the r/SexToys subreddit. It will work with either of the suction-cup dildos above, or any other dildo of your choice. The attached bowls allow you to mount your dildo at an angle if desired: the larger bowl is good for forward-facing and the smaller one for upward-facing. You can use one bowl centered on the shelf or both if desired.

Materials

IKEA Bergshult shelf
11” IKEA Blanda Blank serving bowl, 7” long 1/2” carriage bolt with washer and nut
8” IKEA Blanda Blank serving bowl, 5” long 1/2” carriage bolt with washer and nut
Grippy industrial floor tape
Drill with a 1/2” bit
Socket wrench
Dremel (optional)
Eye protection

Step-by-Step Guide

Place two rows of grippy tape on the bottom of the shelf.
Mark the locations on the shelf where you want to drill the holes for the bolts.
Using the drill with the 1/2” bit, carefully drill holes in the marked locations on the shelf. You will need to wear eye protection.
Insert the carriage bolts through the drilled holes from the bottom side of the shelf. Place a washer and a nut on the underside of each bolt and tighten them using a socket wrench.
Attach the bowls to the carriage bolts by placing them over the bolts. Dremel the holes if necessary so the bowls sit flush. Tighten the nuts to hold the bowls in place.

Not Safe at All Ideas

We wrote above that we’ve looked at lots of ideas for DIY suction-cup dildos, and we’ve brought you the best. These are some of the worst, and you should definitely not try them in any way, shape, or form. They are very likely to injure you and/or your partner.

Unsafe Materials: Any toy used internally, or toys like homemade pussy pumps, should be made with body-safe, non-porous materials so that it can be thoroughly cleaned. These components are not always easy to find, so we see projects made with jelly plastic or even 3-D printed materials. These are not safe and should not go in anyone’s body.
Unstable Mounting Surfaces: Whether you’re using a DIY suction-cup dildo or a purchased one, or even a homemade sex machine, you need to mount it on a surface that is smooth and flat so that you achieve the maximum possible suction. And you should absolutely steer clear of fragile surfaces such as mirrors or windows; if they should shatter (and that is quite possible), you risk glass shards in your vagina or anus.
Homemade Adhesives: Even if you’re determined to DIY everything else, please buy adhesives that have been thoroughly tested. This is the weakest spot of your whole contraption and you don’t need to amplify that by using untried concoctions.

Why Is It Better to Buy a Commercial Product?

The engineers and designers who work on sex toys have knowledge in material science, manufacturing, and most importantly, safety testing. It is their job to not put their employers at risk, and one of the ways they do that is making products that don’t put customers at risk. Other reasons to buy from established manufacturers and retailers include:

Quality: Sex toys produced by professionals are made with high-end materials and finishes. This usually looks like silky, seamless silicone. Of course, this is sensually pleasing but it’s also important for health and safety. Materials with a smooth finish are easier to clean, because seams and pores and nicks have a tendency to harbor bacteria and other contaminants. We recommend the Lovehoney Curved suction-cup dildo, made from lush body-safe silicone. The tapered tip eases insertion and the curved shaft targets sensitive areas like the G-spot or prostate.
Durability: Manufacturers test sex toys for safety, and they also test them for durability. No one wants to spend big money on toys that don’t stand up to enthusiastic enjoyment. DIY toys don’t come with that kind of assurance, and you might find yourself being let down at the most inconvenient moment. The Vixskin Maverick is built to last. It has the strongest suction of all the dildos we tested, so you can count on it holding tight over and over.
Convenience: Do you want to spend your weekend shopping for materials, measuring and marking and gluing, and then cleaning up? Or would you rather unbox your new toy and get busy with it?
