Depth Training Dildos

Depth training dildos are long dildos made for taking more length over time, a little at a time (there's no prize for rushing). Most are slim tentacles with suckers, and one is ribbed all the way down. For anal depth training, go by insertable length, not the size name. More curls live in tentacle dildos, more girth in huge dildos.

What is a depth training dildo? (The short version)

A depth training dildo is a long dildo built for length rather than girth. It stays fairly slim along the shaft, so you can work up to taking more of it over time, a bit at a time. Most of ours are tentacles with suckers; the Depth Trainer is ribbed all the way down instead.

Ours are platinum cure silicone with a flared base, so they're body safe and safe for anal depth training. Want more tentacles? See all our tentacle dildos.

Depth trainer firmness (pick your squish)

  • Super Soft: our best seller, and the one we'd pick for a first depth trainer. Bends and follows your curves.
  • Squishy Soft: our softest and the most forgiving (basically a marshmallow with ambition, a very long one).
  • Medium: holds its shape, so you feel every sucker and rib.

Can't decide? Super Soft. The firmness guide has the details.

Are depth training dildos safe? (Ours are. Here's the boring bit.)

Every depth trainer is platinum cure silicone, which is non porous, phthalate free and easy to sterilise. Every model has a flared base, so it's safe for anal. Go slowly, use plenty of lube and stop if it hurts. Water, silicone and oil based lube all work with our silicone. The suckers trap lube, so give them a proper wash after. The care guide covers cleaning and storage.

Find your depth trainer

From a sensible first step to the deep end. Here's which is which.

Shape first, size later (on the product page). One rule: go by insertable length, not the size name.
