Mutual stimulation device

1. A method of providing sexual stimulation between first and second penises, the method comprising the steps of:

providing a body including first and second openings on a front face, wherein first and second channels extend into the body from the first and second openings, respectively, along first and second longitudinal axes, respectively, that tend toward each other within the body, wherein the first and second channels partially merge to form a chamber, wherein the chamber has a lemniscate shape about the first and second longitudinal axes;

inserting the first penis and the second penis into each of the first and second openings, respectively, such that the first and second penises contact each other within the chamber of the body and do not contact each other immediately adjacent the openings on the front face of the body; and

inserting the first and second penises further into the chamber such that the first and second penises move along the respective longitudinal axes and contact the inside surface of the chamber, the lemniscate shape of the chamber providing alignment of the first and second penises such that an underside of each penis is in contact with the other.

2. A method of providing sexual stimulation between first and second penises of first and second users, respectively, the method comprising the steps of:

providing a mutual sexual stimulation device including a body including;

first and second openings on a front face, wherein first and second channels extend into the body from the first and second openings, respectively, along first and second longitudinal axes, respectively, toward first and second internal ends, respectively;

wherein the first and second longitudinal axes tend toward each other within the body, and wherein first and second diameters of the first and second channels, respectively, taper along the first and second longitudinal axes, respectively, toward the chamber to increase compressive forces on the first and second penises; and

wherein the first and second channels partially merge to form a chamber adjacent to the first and second internal ends, respectively; and

inserting the first penis and the second penis into each of the first and second openings, respectively, such that the first and second penises contact each other within the chamber of the body; and

inserting the first and second penises further into the chamber such that the first and second penises move along the respective longitudinal axes and contact the inside surface of the chamber such that an underside of each penis is in contact with the other.

3. The method of claim 2 , further including the step of separating the first penis and the second penis by a barrier adjacent to the openings.

4. The method of claim 2 , wherein the body of the mutual sexual stimulation device has a block shape including first and second opposing flat surfaces, and further comprising the step of positioning the first and second flat surfaces against a first body and a second body, respectively, of the first user and the second user, respectively.

5. A mutual sexual stimulation device for receiving and aligning first and second undersides of first and second male genitalia, the mutual sexual stimulation device comprising:

a body including first and second openings on a front face, wherein first and second channels extend into the body from the first and second openings, respectively, along first and second longitudinal axes, respectively, toward first and second internal ends, respectively;

wherein the first and second longitudinal axes tend toward each other within the body;

wherein the first and second channels partially merge to form a chamber adjacent to the first and second internal ends, respectively; and

wherein first and second diameters of the first and second channels, respectively, taper along the first and second longitudinal axes, respectively, toward the chamber to increase compressive forces on the first and second male genitalia.

6. The mutual sexual stimulation device of claim 5 , wherein the body is a thermoplastic elastomer.

7. The mutual sexual stimulation device of claim 5 , wherein the body is silicone.

8. The mutual sexual stimulation device of claim 5 , wherein the body is one-piece.

9. The mutual sexual stimulation device of claim 5 , further including an outer sleeve surrounding a portion of the body.

10. The mutual sexual stimulation device of claim 9 , wherein the body comprises a first material and the outer sleeve comprises a second material that is more rigid than the first material.

11. The mutual sexual stimulation device of claim 10 , wherein the first material is silicone.

12. The mutual sexual stimulation device of claim 5 , wherein an angle formed between the first and second longitudinal axes by the intersection of the longitudinal axes is between 5 and 15 degrees.

13. The mutual sexual stimulation device of claim 5 , wherein an inner surface of the chamber includes surface texture.

14. The mutual sexual stimulation device of claim 5 , further including a third opening at a second end of the chamber.

15. The mutual sexual stimulation device of claim 5 , wherein the tapering of the first and second diameter of the first and second channels, respectively, increases friction near the glans of the respective male genitalia.

16. The mutual sexual stimulation device of claim 15 , wherein the first and second longitudinal axes tending toward each other increases friction near the glans of the respective male genitalia.

17. The mutual sexual stimulation device of claim 5 , wherein the body has a block shape including first and second opposing flat surfaces.
