How to Warm Up a Dildo Safely

Last Updated on October 6, 2026 by Nikita

Quick Answer

The easiest way to warm up a dildo is to place it in warm—not boiling—water for a few minutes, then dry it and check the temperature against your forearm before use.

For waterproof silicone, glass, and stainless-steel dildos, warm water is usually the simplest option. Body heat also works when you only want to take away the initial chill.

Avoid putting a dildo in the microwave, oven, or directly against a very hot heating element. Motorized or rechargeable toys need even more caution because heat and electronics are not a good combination.

The most important part is checking the instructions for your particular toy, since the safest method depends on its material and whether it contains electronics.

There is a surprisingly big difference between a dildo that feels warm and one that simply doesn’t feel cold.

Most of the time, the second one is all you actually need.

A dildo stored in a drawer may only be at normal room temperature, yet silicone, glass, and especially metal can feel noticeably cool against warm skin. During partnered play, that sudden temperature change can be distracting enough to interrupt the moment.

That is probably why the same solutions come up again and again whenever people talk about warming toys: warm water, body heat, or briefly placing the toy near a gentle heat source.

The trick is warming it evenly without overheating it or damaging the material.

The Best Method: Warm Water

For most waterproof, non-electronic dildos, warm water is the method I would start with.

Fill a bowl, sink, or large cup with comfortably warm water and place the dildo in it for a few minutes. You can also run warm water over the surface if you are in more of a hurry.

Glass and metal toys are particularly good at changing temperature. Lovehoney, for example, specifically recommends warming compatible glass and metal toys in hot tap water and checking the temperature on the forearm before use.

A few things make this work better:

• Use comfortably warm water rather than boiling water.
• Give thicker toys a little longer because the center stays cooler than the surface.
• Dry the dildo thoroughly before adding lubricant.
• Test several areas of the toy against your inner forearm before use.

The last step matters more than people think. A toy can feel acceptable in your hand while still being hotter than you want on more sensitive skin.

A Mug or Insulated Cup Works Surprisingly Well

One of the more practical ideas that comes up in real-world discussions is using a large mug or insulated cup filled with warm water.

It sounds almost too simple, but it solves two problems.

First, you don’t have to leave a dildo floating in the bathroom sink. Second, an insulated container keeps the water warm while you are doing everything else.

Just remember that putting a large toy into a full cup displaces quite a bit of water, so don’t fill it all the way to the top.

Use Your Own Body Heat

If the goal is only to remove the cold feeling rather than deliberately create temperature play, body heat may be enough.

People commonly warm a dildo:

• between their thighs
• underneath a blanket beside them
• against the stomach
• under an arm
• wrapped in a clean cloth and held close to the body

This method is slower than water, but it has one major advantage: it is difficult to accidentally make the dildo excessively hot.

It also works well when using a toy is spontaneous. Instead of stopping everything to prepare it, keep it close to your body for several minutes while you’re getting comfortable.

Silicone tends to work particularly well this way because you normally only need to take the cool edge off the surface.

Can You Use a Heating Pad?

A heating pad can work, but I would treat it as a secondary method rather than the default.

Wrap the dildo in a clean towel and use the lowest comfortable setting for a short period. Check it frequently rather than leaving it unattended.

The goal is gradual warming, not heating the dildo as quickly as possible.

Avoid placing rechargeable, vibrating, thrusting, app-controlled, or otherwise electronic toys directly on a heating pad unless the manufacturer specifically says the product can be warmed this way.

Rechargeable electronics and unnecessary external heat are simply a combination worth avoiding.

A warm-water bath is much easier to control for a basic waterproof dildo.

What About a Towel Warmer?

This is another idea that appears fairly often, especially with strap-on play.

A warm towel wrapped around a dildo can gently bring the surface closer to body temperature without exposing it to direct heat.

The important distinction is warm towel versus extremely hot towel.

If you use this approach, unwrap the dildo and test the entire insertable portion before use. Don’t assume it is safe just because the towel itself feels tolerable.

Also check that the material is suitable for heat in the first place.

Warming Silicone Dildos

High-quality 100% silicone is fairly forgiving, but that doesn’t mean every product described as “silicone” should be treated identically.

A simple non-motorized silicone dildo can generally be washed with warm water, and some 100% silicone toys can even be boiled for sanitation. However, boiling is a cleaning method—not the method I would recommend simply for warming a toy before use. Motorized toys should not be boiled.

For everyday warming, stick with:

warm water → dry → temperature check → lubricant

That is much easier to control.

If you’re unsure whether the toy is actually 100% silicone, follow its manufacturer’s care instructions rather than assuming it can handle high heat.

For silicone toys, material matters when choosing a warming method. You can also browse our silicone dildos to compare different shapes and designs before deciding which warming method fits the toy best.

Warming a Glass Dildo

Glass is probably the material where warming makes the biggest noticeable difference.

Borosilicate glass responds quickly to temperature and holds that temperature longer than soft silicone.

Place the dildo in warm water for several minutes, remove it, dry it, and test it on your forearm.

Some glass-toy manufacturers specifically promote warm-water temperature play.

What I would not do is move a glass dildo between extreme temperatures.

There is rarely any reason to go from freezing cold to very hot water, and dramatic temperature changes put unnecessary stress on glass.

Inspect a glass dildo occasionally as well. If you notice a chip, crack, or other surface damage, stop using it.

Glass responds especially well to temperature changes, which makes warming method and timing more noticeable. You can browse our glass dildos to compare different shapes and styles.

Warming a Stainless-Steel Dildo

Metal feels particularly cold at first because it transfers heat efficiently.

The upside is that it also responds very well to warm water.

A few minutes in warm tap water usually makes a stainless-steel toy feel noticeably different. Like glass, metal also holds temperature better than silicone, so start conservatively.

You can always make it slightly warmer afterward.

Cooling down a toy that you made far too hot is much less convenient.

Metal toys transfer temperature quickly, so even a short warm-water soak can noticeably change how they feel. You can browse our metal dildos to compare different shapes and designs.

What About an Electronic Dildo?

This is where the rules change.

A dildo with:

• vibration
• thrusting
• rotating parts
• suction
• a rechargeable battery
• a charging port
• remote control
• app control

should be treated according to its own waterproof rating and care instructions.

“Waterproof” does not automatically mean “safe to heat.”

A waterproof seal tells you something about water resistance. It does not mean the battery, adhesives, motor, seals, and internal components were designed for high temperatures.

For electronic toys, body heat or gently warm running water—if the manufacturer allows it—is the safer direction.

Don’t boil them.

Electronic toys need a little more care around heat, especially models with motors or moving parts. If you’re comparing powered options, you can browse our thrusting dildos and vibrating dildos to compare different powered designs.

Should You Boil a Dildo to Warm It Up?

You may see people recommend this because some non-motorized 100% silicone, stainless-steel, or glass toys can tolerate boiling as part of sanitizing.

That does not make boiling a particularly useful warming method.

A dildo removed from boiling water can obviously be far too hot for immediate body contact, and thicker materials may retain that heat for longer than expected.

Healthline’s toy-cleaning guidance also separates motorized toys from nonmotorized toys: some nonmotorized nonporous toys may tolerate boiling for sanitation, while motorized toys should not be treated that way.

If your only goal is comfortable temperature, warm water accomplishes the job with much less risk.

Don’t Microwave Your Dildo

This is one piece of internet advice I would skip completely.

Microwaves can heat objects unevenly, meaning one area may remain barely warm while another becomes dangerously hot.

More importantly, you often don’t know exactly what is inside a toy.

A seemingly simple dildo may contain:

• different materials
• adhesives
• metallic pigments
• internal structures
• suction-cup components
• electronics

There is almost no advantage to microwaving when warm water takes only a few minutes and gives you much more control.

The same principle applies to ovens, stovetops, hair dryers on high heat, and other aggressive heating methods.

How Warm Should a Dildo Be?

It doesn’t need to feel hot.

For most people trying to avoid the unpleasant “cold toy” sensation, roughly skin-warm is enough.

Rather than chasing a precise temperature, use your own skin as the final check.

Press the dildo against the inside of your forearm for several seconds.

It should feel comfortably warm rather than making you instinctively pull away.

Check more than just the tip, particularly with glass and metal toys. Different parts can warm at different speeds.

Do You Need to Warm It at All?

Not necessarily.

Some people don’t notice the temperature difference. Others actually enjoy cooler toys as part of temperature play.

Warming is simply useful when room-temperature silicone, glass, or metal feels distracting.

There is no ideal dildo temperature that applies to everyone.

That is one reason I like body-temperature warming rather than trying to make a toy genuinely hot: it removes the distracting coldness without making temperature itself the main sensation.

A Simple Routine That Takes Almost No Planning

If you regularly find yourself reaching for a dildo and immediately thinking, this thing is freezing, you don’t need a complicated warming ritual.

Try this:

1. Put the dildo in a large cup or bowl of warm water.
2. Leave it there while you get ready.
3. Remove and dry it.
4. Test it against your forearm.
5. Add lubricant.
6. Use it only when the temperature feels comfortable.

For many toys, the whole process fits naturally into the time you would already spend getting ready.

That may be the biggest lesson from people who actually warm their toys regularly: the simplest methods tend to be the ones people keep using.

FAQ
