Sex machines purchased directly from Orgasm Alley come with either (or both) of two dildo attachment systems, pictured here. Note that dildos are sold seperately.

On the bottom is the Standard Dildo System, shown with and without dildo attached. The Standard system consists of a welded steel platform arm and retaining strap. This strap is sewn from Velcro and webbing. This dildo systems works well with most dildos that have a wide or flared base, particularly "balls."

On the top, also with and without dildo, is the Vac-U-Lock Dildo System (VUL). This machined aluminum plug matches the shape used with Vac-U-Lock dildos (a product of the Doc Johnson Company, originally designed for use with strap-on harnesses). This system does require these specialized dildos.

Which System is Right for You?

This depends primarily on the type of dildos you own (or plan to purchase). If you don't own dildos presently, I do recommend the VUL system. It is easier to use and extremely secure. Obviously, the most flexible solution is to own both dildo systems.

When using the VUL system, I second Doc Johnson's recommendation of a powder lubricant. Their own product has a very controllable applicator, but I do find that talcum powder works just as well (and is cheaper, of course!). This system works by creating a vacuum as air is forced from the dildo recess by the insertion of the plug. Once it's in, it's not going anywhere! Without powder in the connection, it can be very difficult to remove the dildo.
