A great example of a blue dildo is the G Freak Blue Jellie Dong with suction cup by Doc Johnson. This dildo also work very well with the Heeldo.
The vibrator has its place in cinematic history. The great film, Attack of the Blue Dildo was an instant cult classic as soon as it hit the silver screen. Although a B-rated low budget film, this dark, sexy comedy immediately struck a chord with the indie crowd. If you can't find it at a local big-box retailer, check out some of the smaller shops with specialty collections. I have seen it on auction sites and at flea markets. This film is a must seen for anyone who loves a sex toy with their popcorn.
