The Classic Aluminum, a double headed dildo by Luxotiq is sure to please sensationalists and traditionalists alike. This is a really great toy for vaginal penetration. It has two ends, making this accessible for beginners and advanced users, and it has all of the benefits of metal (doesn't need a lot of lube, can be sanitized, awesome for temperature play...) The only real downside to this one is its substantial weight, which can tire you out.
