Industrial design meets slick engineering in new generation of sex toys.

As sex toys have become less taboo and much more popular, the market has expanded at an extraordinary rate. It's now a huge industry, worth upwards of $20 billion in annual sales. Many new designers and engineers, with very legit credentials, have entered the industry, leading to a surge in impressive new devices. The following are a few examples.

This is Crave's Duet, a dual-headed vibrator that charges via USB and can store up to 16GB of digital stuff. Half of it is the rechargeable battery with the Flash memory—convenient to store all your porn—and the other half is the dual-headed vibe.

Crave also makes stealthy flash vibes that look like mascara tubes:

Intensity by Jopen. This device stimulates and exercises - it's intended to provide pleasure while also strengthening the PC muscles.

The Blade by Fleshlight (link NSFW). This is the latest iteration of the Fleshlight, the most popular male masturbatory toy. What makes it different than previous generations of Fleshlights is that it can be squeezed, adding increased pressure. The inner texture was also enhanced.
