Like the rabbit vibrator, suction cup dildos are (for me) a great idea in theory but terrible in execution. I’m no spring chicken anymore and I have the knees of a person twice my age. I can’t deny though that plenty of people love these things. One reason why I have trouble with suction cup dildos is the lack of a compatible surface. The surface has to be completely flat and perfectly smooth, no imperfections that would break the suction seal. Bathroom tiles can sometimes work, but they need to be at least 1/2″ bigger than the base on each side to have a chance at working. Mirrors and windows work, of course. Painted walls though, normally do not. Before you get it in your head that the suction cup is for you, make sure you have a surface that’ll work with it. I see a lot of people buying the porous / possibly-toxic versions way, way too often so I’m providing a list of all known safe versions. There’s a surprisingly larger selection than I expected!
All of our dildos are designed with ergonomics and harness compatibility in mind. As the bases are shaped to conform to the natural curves of the body, this does not readily lend itself to suction cup styles. Whilst the Tantus attachment would definitely fit into the vibe hole for both Fuze and Happy Valley toys, I doubt that it would either be comfortable or function to its full potential, due to the different design criteria of ourselves and Tantus.
Pipedream Fetish Fantasy Elite line has a number of silicone dildos & silicone vibrating dildos with suction cup bases but you know they’re not a company I trust. The price is pretty low for the dildos but I’m just in general unconvinced of their overall quality. I’ve not flame-tested anything from them; until I can get my hands on one to flame test and dissect, I’m reluctant to really recommend them but there they are. There’s such a big line that I can’t really ignore them, and they do offer the vibrating aspect which isn’t common for this list.
The Colours line, from NS Novelties, has 2 sizes of suction cup dildos in 2 colors. The overall styling is realistic, but the colors aren’t (charcoal black and hot pink).
Vixen dildos sometimes have a naturally occurring suction cup base. I contacted Vixen to get the complete current line-up:
Malesation dildos also have a suction cup base, but I’m not sure yet who is carrying this line, it seems pretty new. New York Toy Collective is unknown; I reached out to them, but received no response. If they respond and they have something, I’ll update here. Pleasureworks doesn’t currently have a consistent concave base on their dildos. If you know of any other brands that have a suction-cup base, either by design or as a by-product of a concave base, let me know!
