Vacuum-driven personal device

A method of using a vacuum-driven personal adapter for male sexual stimulation,

• a) the adapter including an elongated primary conduit:
• 1) extending longitudinally from a coupling end to an insertion end,
• (a) the coupling end having a crown that is tapered such that when the crown is inserted into a vacuum hose of a running vacuum, the crown is partially sucked into the vacuum hose to secure the conduit to the vacuum hose via a suction fit,
• (b) the insertion end having a member opening sized to longitudinally receive a penis therethrough;
• 2) having a coupling end aperture that allows air to flow into the conduit, the coupling end aperture allowing a user to throttle negative pressure within the primary conduit by obstructing the coupling end aperture to varying degrees such that a suction level within the primary conduit varies between:
• (a) a minimal suction level when air flow through the coupling end aperture is unobstructed;
• and
• (b) a maximum suction level when the coupling end aperture is closed off against air flow therethrough;
• 3) having a set of primary tuning apertures:
• (a) circumferentially spaced about the primary conduit,
• (b) being positioned proximate to the member opening at the insertion end, and
• (c) configured to allow for variation in air flow as different primary tuning apertures are obstructed to different degrees,
• b) the adapter further including a secondary conduit sized to fit within the primary conduit to decrease a diameter of the member opening, wherein the secondary conduit includes a set of secondary tuning apertures correspondingly spaced such that, when the secondary conduit is inserted into the primary conduit, at least a majority of secondary tuning apertures are alienable with primary tuning apertures,
• c) wherein the method includes the steps of:
• 1) inserting the crown into a vacuum hose and engaging a vacuum device to generate negative pressure in the vacuum hose and thereby secure the primary conduit to the vacuum hose via a suction fit;
• 2) inserting a penis into the primary conduit that is suction fit with the vacuum hose;
• and
• 3. vibrating the penis using air flowing into the primary conduit on its way to the vacuum hose.

• c) wherein the adapter is configured such that,
• 1) when the crown is inserted into a vacuum hose and a vacuum is engaged to generate negative pressure in the vacuum hose and thereby secure the primary conduit to the vacuum hose via a suction fit, and a penis is inserted into the primary conduit with a gap between the penis and an inside of the primary conduit,
• 2) air flows into the primary conduit on its way to the vacuum hose to vibrate the penis, wherein the penis is vibrated without longitudinal motion of the penis in or out of the primary conduit.
