With Suction Cup

Prices start around 11 euros and most of the RealRock range stays under 50 euros; the Doc Johnson ULTRASKYN cocks with a removable Vac-U-Lock suction cup cost about 87 euros. The materials are split roughly equally between TPE and PVC, plus about ten dual density silicone models.

Where a suction cup holds

A suction cup needs a smooth, non-porous surface: tiles, glass, a mirror, glossy metal, sealed wood or a smooth floor. It will not hold on grout lines, textured tiles, wallpaper or fabric. Clean and dry both the surface and the cup, press the cup down firmly from the centre outwards and keep lube off the base, because lube makes it slide. The heavier the dildo and the harder you ride, the more grip you need, so test the hold before you put your full weight on it.

Straight, curved, with balls or clear

Straight models are simple and good for a first ride: the RealRock Straight 14.5 cm is only 2.8 cm wide, and the RealRock Straight 18 cm 3.8 cm, both in see through Crystal Clear TPE. A curved shaft aims at the prostate when you ride facing the right way, like the RealRock Dual Density Silicone Curved 18.5 cm with a firm core under a soft outer layer, or the longer PVC RealRock Curved 23 cm. Balls add realism and a stop at the base, as on the RealRock Curved with Balls 18 cm. For size queens, the RealRock Straight with Balls 30.5 cm has 25 cm insertable and 6 cm diameter. The RealRock Slim Glow in the Dark lights up after time in the light.

Size: insertable length and diameter

The total length includes the base and balls; what goes inside is the insertable length, listed on every product page. Width matters more than length, so compare the diameter with a toy or two fingers you know, which together are roughly 3 to 3.5 cm. If you are new, start around 3 to 3.8 cm wide. Most RealRock shapes come in several lengths, so you can keep a shape you like and go longer or thicker step by step.

Riding, shower and harness

On the floor, sit down onto it slowly and let your own weight set the depth. On the shower wall at hip height you can bend over and back onto it with your hands free. For partner play, a removable Vac-U-Lock suction cup, as on the Doc Johnson Realistic Cock 21 cm, lets the same dildo lock into a Vac-U-Lock harness; models with a flared base fit most harnesses with an O ring, see strap-ons and harnesses. Some sex machines take a dildo on a mount; the machine's product page says which.

Materials and care

TPE is soft and squishy and makes the clear and glow models; PVC is firmer with a soft touch; dual density silicone combines a firm core with a skin like outer layer and is the easiest to clean thoroughly. Use a water-based lube with all of them, on the dildo and on yourself. Wash with warm water and mild soap or a toy cleaner, including the suction cup, dry everything and store each dildo on its own. Use a condom over TPE and PVC models if you share them.
