Dildo Materials Guide: Silicone vs Glass vs Steel vs Realistic

Last updated October 2026 · Written by Casey M., Resident Toy Specialist at Epic Dildos.

TL;DR

Silicone is the best all round choice: soft, non porous and easy to clean. Glass and steel are firm and great for temperature play. Realistic materials such as UltraSkyn feel amazing but need more care. Jelly and PVC are cheap but porous.

Material Comparison

Material Feel Porous? Lube Best for
Silicone Soft to firm No Water based Almost everyone
Glass Hard, smooth No Any Temperature play, firm pressure
Stainless steel Hard, heavy No Any Temperature play, weight
UltraSkyn and realistic blends Very soft, skin-like Yes Water based Realism
Jelly or PVC Soft, rubbery Yes Water based Tight budgets, with a condom

Silicone

Non porous, so it cleans thoroughly, and it comes in everything from squishy to firm. It is a favourite for girthy dildos and dual density toys. Downsides: it costs more, and silicone lube can damage it. Pure silicone rarely causes reactions, but check the listing, since not every product labelled "silicone" is 100% silicone.

Glass

Smooth, firm and non porous. Warm it in water or chill it in the fridge for temperature play. Check for chips before each use and do not use it if damaged.

Stainless Steel

Heavy, firm and practically indestructible. Holds temperature well. The weight takes getting used to.

Realistic Materials: UltraSkyn, Vixskin and More

UltraSkyn is Doc Johnson's own soft, skin-like material. It feels very realistic but is not silicone and is somewhat porous, so wash it well, dry it fully and store it on its own. Vixskin is different: it is dual density platinum silicone, so it is non porous. Full comparison in our UltraSkyn, VixSkin and SkinTech guide.

Jelly and PVC

Cheap and colourful, but porous, and cheaper ones may contain phthalates. If you choose one, use a condom over it and replace it once it turns sticky, cloudy or smelly.

Frequently Asked Questions

What is the safest dildo material?

Non porous materials: silicone, glass and stainless steel. They can be cleaned thoroughly and do not hold bacteria.

Is silicone hypoallergenic?

Pure silicone rarely causes reactions, but not every product is pure silicone and anyone can react to anything. Check the listing and patch test if you have sensitive skin.

Can I use silicone lube with silicone toys?

It is safest not to. Silicone lube can make some silicone toys tacky or damaged. Water based lube works with everything.

Are jelly or PVC dildos safe?

They are porous and cheaper ones may contain phthalates. If you buy one, use a condom over it and replace it when it gets sticky or discoloured.
