Usage The Feeldoe is designed to be used in the same way and for the same purposes as a conventional strap-on dildo. Instead of being attached to the user by means of straps, the user inserts the tail end of the device (known on the Feeldoe website as the pony) [2] into their vagina or rectum. The tail stimulates the top user's g-spot or prostate. The head of the Feeldoe (known on the Feeldoe website as the horse) is used to penetrate in the same manner as a conventional dildo. The product name, "Feeldoe", is a Registered Trademark belonging to Erogenics, Inc. which is the product inventor's corporation.
