How To Use A Suction Cup Dildo

There are several ways you can use a suction cup dildo and a variety of pleasurable positions that work well with this type of toy.

Before you use a dildo, make sure you have plenty of lube handy as it’ll provide a much more enjoyable experience.

A good water based lubricant is ideal. Don’t use household lubes such as petroleum jelly, hand soap, or moisturizers as these can damage the surface of some dildos over time. Always use a lube that’s intended for sex and the material of your toy.  

Here are a few positions that work great with suction cup dildos:

Doggy Style – This is one of the preferred positions with a partner as they can thrust the dildo just like a penis. You can attach the toy to a surface if you like and get off on nearly any surface.

Second Penis – Two are better than one, right? Suction cup dildos are great for anal play while your partner is already in your pussy.

Sitting – You could sit on the dildo while giving your partner oral sex making it pleasurable for both people involved.

Threesome – The dildo can take the place of another penis and be used to act out threesome fantasies.

Spooning –  This works great while spooning as it can reach areas of a body that you might not be able to if you’re smaller in size.

What To Put A Suction Cup Dildo To?

A dildo with a suction cup will work on many different surfaces. In general, you should use some lube on the base to get it to stick better. In some cases, it will adhere just fine to various surfaces.

Here are the best surfaces to use your suction cup dildo.

Bathtub The bathtub works excellently as the water will help hold the dildo in place. You can put it on the bottom of the tub and sit on it or put it against the wall and back up against the cock.

Floor – The suction cup also attaches excellent to hard floors. You can’t use it on the carpet, but hardwood or tiled floors are perfect. If you use lube or water on the base, make note that it could stain, so see if it sticks without these lubricants first or be sure to seek out one that won’t stain.

Chair – You can use the dildo on a chair with a solid wood surface. It won’t work on ones with upholstery, but a regular wood chair will work fine; stick, slide, and ride.

Mirror – You can add the dildo to a mirror which is great if you’re someone who likes to watch. A full-length mirror will work great and adds a different perspective to foreplay or masturbating.

Headboard – If you have a wood headboard on your bed, be sure to experiment and slap it on. If you’re having troubles getting it to stick, lightly wet the suction cup and reapply.
