8. The device of claim 1 , wherein the expandable portion is configured to be inserted into a vagina.

9. The device of claim 1 comprising a pump in communication with the expandable portion and configured to cause expansion of the expandable portion.

10. The device of claim 1 , wherein the electrode is formed of an expandable material.

11. The device of claim 10 , wherein the expandable material is an electrically conductive silicone rubber.

12. The device of claim 1 , wherein a radial thickness of the first portion is greater than a radial thickness of the second portion.

13. The device of claim 1 , wherein the second portion comprises at least one fold.

14. A stimulation device for creating a pleasurable sensation in a user comprising:

a housing;

a shaft having a proximal end and a distal end, the proximal end being interconnected to the housing;

an operative portion located between the proximal end and the distal end and configured to be located within at least one of a vagina, an anal canal, and a rectum when the device is in an inserted position;

only one balloon circumferentially surrounding the operative portion of the shaft; and

a first electrode and a second electrode, the first and second electrodes coupled to an outer surface of the balloon and configured to cause a contraction of a muscle in communication with the electrodes;

wherein the balloon is configured to selectively inflate such that the first and second electrodes press against at least one wall of the at least one of a vagina, an anal canal, and a rectum, wherein the balloon comprises a folded portion having at least one fold and configured to cause the balloon to inflate in a radially non-uniform manner, and wherein neither the first electrode nor the second electrode is directly coupled to the folded portion.

15. The device of claim 14 , wherein the only one balloon surrounds the entire portion of the shaft located within the at least one of a vagina, an anal canal, and a rectum when the device is in an inserted position.

16. The device of claim 14 , wherein the housing is coupled to the proximal end of the shaft so as to retain and fluidly seal the balloon to the shaft.

17. The device of claim 14 , wherein the housing covers a portion of the balloon.

18. The device of claim 14 , further comprising a pump located in the housing, in communication with the balloon, and configured to cause inflation of the balloon.

19. The device of claim 14 , wherein the entirety of the housing is not covered by the balloon.

20. A stimulation device for creating a pleasurable sensation in a user comprising:

a shaft having a proximal end and a distal end, the proximal end being coupled to a handle;

an operative portion located between the proximal end and the distal end and configured to be located within a vagina when the device is in an inserted position;

an expandable portion comprising an outer surface and configured to assume a plurality of states of expansion between minimum expansion and maximum expansion, the expandable portion circumferentially surrounding the operative portion of the shaft;

a first electrode and a second electrode, the first and second electrodes configured to cause a contraction of a muscle in communication with the electrodes, the first electrode coupled to a first portion of the outer surface of the expandable portion, and the second electrode coupled to a third portion of the outer surface of the expandable portion, wherein the expandable portion comprises a second portion having at least one fold, wherein neither the first electrode nor the second electrode is directly coupled to the second portion, and wherein the first, second, and third portions cooperate to cause the expandable portion to expand in a circumferentially non-uniform manner, and;

a first vibrating element extending away from the outer surface of the expandable portion and configured to impart vibration to a user's Gräfenberg Spot;

a second vibrating element configured to impart vibration to a first portion of user's body;

a passageway for permitting a fluid from outside of the stimulation device to enter the expandable portion, the passageway having at least one check valve along the passageway;

a pump in communication with the expandable portion and configured to move the fluid through the passageway to cause inflation of the expandable portion such that at least one of the first electrode, the second electrode, and the first vibrating element press against a vaginal wall; and

processing electronics configured to cause an electrical signal in the electrodes, to control an aspect of vibration of the first vibrating element, and to control an aspect of vibration of the second vibrating element.
