RELATED APPLICATION 
     The present application claims the benefit under title 35, United States Code, Section ii 9(e) of U.S. provisional application No. 60/362,862, filed Mar. 8, 2002 entitled “SELF LUBRICATING SEX AIDS”. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to self lubricating sex aids for use in avoiding irritation or pain during sexual activities or during auto erotic sex activities, while concomitantly increasing the pleasure of the users or user. 
     2. Description of the Prior 
     The use of sex aids of known designs and configurations is well known in the prior art. More specifically, sex aids of known designs and configurations heretofore devised and utilized for the purpose of increasing sexual stimulation through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations. 
     Among the large number of prior art sex aids of known designs and configurations are, by way of example, those taught in U.S. Pat. No. 5,690,603 which discloses a sexual stimulator that contains a vibrator and can include a fluid chamber that allows the flow of the fluid from part to part within the sealed chamber; U.S. Pat. No. 6,280,403 which discloses a massage device that includes a sealable chamber to include, for example, warm water, but from which chamber no fluid is allowed to flow to the skin or internal private parts of the user; and U.S. Pat. No. 6,322,493 which teaches a clitoral stimulator that directly dispenses a stimulating compound. None of these prior art systems include normally open through-holes from their chambers to the surfaces of the devices. In fact, as noted, U.S. Pat. Nos. 5,690,603 and 6,280,403 are rigorously designed to avoid allowing any fluid to exit from their chambers during use. It is also noted that during the use of many sex toys it is not unusual to apply moisturizing fluid by hand or by other mean to the skin or internal private parts of the user, thereby requiring unwanted interruptions before or distractions during such activity. 
     Therefore, it can be appreciated that there exists a previously unappreciated need for a new and improved sex aid that allows a lubricating fluid to exit from normally open through-holes from chambers associated with the device to the surface of the device during use for the purpose of avoiding irritation or pain during sexual activities or during auto erotic sex activities, while concomitantly serving the purpose of increasing the pleasure of the users or user during such activities. 
     SUMMARY OF THE INVENTION 
     In this respect, the sex aids according to the present invention substantially depart from the conventional concepts and designs of the prior art, and in so doing has as an object to provide various apparatus primarily developed for the purpose of avoiding irritation or pain during sexual activities or during auto erotic sex activities, while concomitantly increasing the pleasure of the users or user during sexual activity by intentionally having fluid exit through normally open through-holes from chambers associated with the device during use. In this regard, the present invention substantially fulfills a previously unappreciated need. 
     In view of the limitations inherent in the sex aids of known designs and configurations now known in the prior art, the present invention provides new and improved self-lubricating sex aids that allow the users or user to avoid irritation or pain during sexual activities, or during auto erotic sex activities, while concomitantly increasing the pleasure of the users or user. As such, the general purpose of the present invention, which is described in greater detail below, is to provide a new and improved self lubricating sex aids and methods which have all the advantages of the prior art and none of the disadvantages. 
     To attain such results, the present invention essentially comprises modifications to sex aid systems to provide new and improved systems for use in avoiding irritation or pain during sexual activities or during self stimulated sex activities, while concomitantly increasing the pleasure of the users or user. The new and improved sex aid systems uniformly comprise the modification of or addition to art known sex aid systems which provides for the self lubrication of the sex aids for the users or user, especially at the surface or surfaces of the sex aid that contact and stimulate the external or internal erotic surfaces of the users or user. 
     In one format, where the volume and the shape of the sex aid will allow, each new and improved sex aid system is modified to include a hollow chamber associated with the sex aid, either internal or external to the sex aid. Such new and improved sex aids, in accordance with the present invention, are further modified to include at least one or more normally open through-hole extending from the added chamber to the surface portions of each sex aid, and especially to the surface portions of each sex aid that are intended to contact and stimulate the external or internal erotic surfaces of the users or user. 
     In the operation of the present invention, an off the shelf water-soluble moisturizing fluid, or sterile water or other non-irritating fluid is poured into the hollow chamber. In each instance the moisturizing fluid is preferably inert to both plastic and to rubber. Each such new and improved sex aid system may be manipulated for its desired purpose by the users or user, or may include or be attached to a vibrator device or other energizing apparatus. In operation, external air pressure and the motion or vibration of each new and improved sex aid system causes the fluid present in the hollow chamber to exit through the through-hole or holes to lubricate any external or internal body parts with which the hole or holes are placed in contact. 
     In another format, where the volume and the shape of the sex aid will not allow it to be modified to include an internal chamber, a fluid reservoir may be provided that is either attached directly to the sex aid or remotely connected, say through a tube, but in either case to normally open through-holes to lubricate any external or internal body parts with which the hole or holes are placed in contact with the device. In such modifications in accordance with the present invention, the attached or remote reservoir is in fluid contact with the new and improved sex aids of the present invention, which sex aids are also modified to include at least one or more hole extending from connection with the reservoir to the surface portions of each such sex aid, and especially to the surface portions of each such sex aid that are intended to contact the external or internal surfaces of the users or user. Those modifications with an added external reservoir also operate in response to external air pressure and the motion or vibration of each new and improved sex aid system, to cause the fluid present in the reservoir to exit through the hole or holes to lubricate any external or internal body parts with which the hole or holes are placed in contact. 
     It has been determined that the preferred diameter of the through-holes added to the sex aids of the present invention for use with lubricating fluids is in the size range of from about 1.5 mm to about 3.5 mm, although smaller or larger diameter holes, say in the range of from about 0.5 mm to about 5 mm may work, depending on the viscosity of the fluid and the energy output of any associated vibrator or other associated stimulation. The sex aids with which the present invention can be used may be of any hard, soft or pliable material, say plastic, plastic-jelly, simulated skin, rubber, silicone and the like. The sex aids may be active or passive, say vibrating or non-vibrating. Non-limiting examples of the sex aids that may be improved by the present invention are dongs, dongs with simulated testicles, dildos, double dildos, attachable prosthetic penises, strap-on penises with or without an opposed extension, male masturbator tubes, simulated vaginas, blow-up dolls with orifices, activated simulated tongues, anal plugs, anal probes, G-spot vibrators, double dongs, penis rings with clitoral stimulators, female stimulators, and the like, all as are well known in the art. It is also apparent that any and all new sex aids may be modified for the practice of the present invention. 
     In one specific embodiment, a state of the art hand-held reciprocating vibrator base is connected to a stimulating element. The stimulating element is modified to have an added hollow internal chamber. At least one or more hole extends from the added hollow internal chamber in open fluid contact with the surface of the stimulating element. In operation, an off the shelf water soluble moisturizing fluid is poured into the added hollow internal chamber. When used, vibration and external air pressure causes the moisturizing fluid to egress from the chamber through the holes to lubricate the body parts with which the stimulating element is placed in contact to thereby avoid irritation or pain during sexual activities or during auto erotic sex activities, while concomitantly increasing the pleasure of the users or user and thereby meeting one of the objects of the present invention. 
     These and other objects of the present invention will become apparent to those skilled in the art from the following detailed description and accompanying drawings, showing the contemplated novel construction, combination, and elements as herein described, and more particularly defined by the appended claims, it being understood that changes in the precise embodiments to the herein disclosed invention are meant to be included as coming within the scope of the claims, except insofar as they may be precluded by the prior art.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to FIGS. 1-3, one preferred embodiment of the present invention, generally  10 , a state of the art hand-held reciprocating vibrator base  12 , including a standard threaded male extension  14  for connection to a stimulating element  16 , is shown. Stimulating element  16  is shown to be modified to define a hollow internal chamber  18 , FIG. 3, along with a standard threaded internal female receiver  20 . Stimulating element  16  also includes a plurality of through-holes  22  extending in open contact with added hollow internal chamber  18  to provide open fluid contact to the surface of the stimulating element  16 . Holes  22  have a diameter in the size range of from about 1.5 mm to about 3.5 mm. In operation, an off the shelf water-soluble moisturizing fluid  24  is poured from container  26  into internal chamber  18  within stimulating element  16 . The size of through-holes  22  and the viscosity and surface tension of moisturizing fluid  24  is such that the moisturizing fluid  24  tends to stay within internal chamber  18  within stimulating element  16 . As best shown in FIG. 3, hand-held reciprocating vibrator base  12  carries an imbedded electrically powered vibrator motor  28  that may be energized by dry cell batteries  32  removably carried within hand-held reciprocating vibrator base  12 . Base cap  34  is removable to allow access to batteries  32 , and also serves as a rotatable switch to turn electrically powered vibrator motor  28  on and off, and in preferred embodiments to vary the amplitude and speed of electrically powered vibrator motor  28 . In their current embodiment, the exterior of both reciprocating vibrator base  12  and stimulating element  16  are constructed of rigid plastic, although modification of stimulating element  16  to soft rubber or silicone rubber is contemplated as being within the teaching of the present invention. 
     In operation, after moisturizing fluid  24  has been placed within internal chamber  18  of stimulating element  22 , movement, vibration and external air pressure causes moisturizing fluid  24  to egress from chamber  18  through-holes  22  to lubricate the body parts with which the stimulating element  16  is placed in contact. The presence of moisturizing fluid  24  assists in avoiding irritation or pain during sexual activities or during autoerotic sex activities, while concomitantly increasing the pleasure of the users or user, and without requiring interruptions before or distractions during such activity to apply moisturizing fluid by hand or by other means. 
     Now referring to FIGS. 4 and 5, another embodiment the present invention is shown. In this embodiment a simulated vagina sex toy, generally  40 , is shown. In the embodiment shown a flaccid soft plastic male masturbator tube  42 , including internal stimulator knobs  43  is attached. Simulated vagina portion  44  is generally toroidal in shape, and, in the embodiment illustrated, includes simulated vaginal lips  46 . As best shown in FIG. 5, included in vagina portion  44  is an electrically powered imbedded reciprocating vibrating element  28  connected by wires  48  to an external battery  32  powered multi-speed battery pack  52 . Also carried by vagina portion  44  is a reservoir  54  including a closure cap  56 . A plurality of internal tubes  58  each extends from hollow reservoir  54  to provide open fluid contact to holes  62  at the surface of simulated vagina portion  44 . As with the previous embodiment, holes  62  have a diameter in the size range of from about 1.5 mm to about 3.5 mm. 
     In operation, closure cap  56  is opened and an off the shelf water-soluble moisturizing fluid, not shown, is poured into reservoir  54  carried by vagina portion  44 . Once again the size of through-holes  62  and the viscosity and surface tension of the moisturizing fluid is such that the moisturizing fluid tends to stay within through-holes  62  within vagina portion  44 . A rotatable switch  64  integrated with multi-speed battery pack  52  is capable of turning electrically powered vibrator element  28  on and off, and in preferred embodiments, to vary the amplitude and speed of electrically powered vibrator motor  28 . In operation, after moisturizing fluid has been placed within reservoir  54  of vagina portion  44 , after which movement, vibration and external air pressure causes moisturizing fluid to egress from reservoir  54  through-holes  62  to lubricate the body parts with which the vagina portion  44  is placed in contact. The moisturizing fluid assists in avoiding irritation or pain during sexual activities or during autoerotic sex activities, while concomitantly increasing the pleasure of the user, and without requiring interruptions before or distractions during such activity to apply moisturizing fluid by hand or by other means. 
     In preferred embodiments, vagina portion  44  is composed of a jelly form of silicone plastic, and, where desired may be scented to enhance the pleasure of using the system. While reservoir  54  is shown to be connected to vagina portion  44 , it may be readily seen that such a reservoir may be separate and connected, for example by tubes, to vagina portion  44 . 
     Finally, referring to FIGS. 6 and 7 yet another embodiment of the present invention is shown. In this embodiment a double dildo, generally  70 , is shown in an explode view. In the embodiment shown first and second dildo elements, generally  72  and  74  respectively, are shown. As best shown in FIG. 7, included in both dildo portions  72  and  74  is a hollow reservoir  76  including a plurality of tubes  78 , each extending from each hollow reservoir  76  to provide open fluid contact to holes  80  at the surfaces of first and second dildo elements  72  and  74 . Holes  80  have a diameter in the size range of from about 2 mm to about 5 mm. 
     As shown, a dildo portion  72  includes a standard threaded female internal receiver  82 . Threaded female internal receiver  82  defines an annular opening leading to its hollow reservoir  76  for ease of filling its reservoir  76  with moisturizing fluid. Similarly, dildo portion  74  includes a standard threaded external male element  84 . Threaded male element  84  also defines an annular opening leading to its respective hollow reservoir  76  for ease of filling that reservoir  76  with moisturizing fluid. Dildo portions  72  and  74  are preferably constructed of semi-rigid, bendable soft rubber or plastic. Unlike the previous two embodiments, double dildo  70  includes no vibrator element. 
     In operation, after moisturizing fluid is placed within reservoirs  76 , movement and external air pressure causes moisturizing fluid to egress from reservoirs  76  through the plurality of tubes  78 , to holes  80  at the surfaces of first and second dildo elements  72  and  74  to thereby lubricate the body parts with which dildo portions  72  and  74  are placed in contact. In such use, once again the moisturizing fluid assists in avoiding irritation or pain during sexual activities or during autoerotic sex activities, while concomitantly increasing the pleasure of the users or user, and without requiring interruptions before, or distractions during, such activity to apply moisturizing fluid by hand or by other means. While not shown, a central plug element may be placed in use between dildo portions  72  and  74 . For use with the embodiment shown in FIGS. 6 and 7 the plug would have appropriate threaded male and female elements for use in connecting dildo portions  72  and  74  together. In the alternative, dildo portions  72  and  74  could be modified to both carry threaded female elements and the plug have appropriate threaded male elements for use in connecting dildo portions  72  and  74  together. Similarly, dildo portions  72  and  74  could be modified to both carry threaded male elements and the plug has appropriate threaded female elements for use in connecting dildo portions  72  and  74  together. The benefit of using such plugs is that they will allow one reservoir  76  in one dildo portion portions  72  or  74  to be filled and then closed with such a plug, after which the remaining dildo portion  72  or  74  to be filled and then easily connected to the already plugged dildo portion. 
     It is possible for the devices of the present invention to be used for other purposes, such as massage of any part of the body. Regardless of how the devices are used, they are best used if they are cleaned before and after each use. 
     As noted in the summary, the concept of the present invention as shown i can be easily applied to many other forms of sex aid, as listed in the summary. 
     The foregoing exemplary descriptions and the illustrative preferred embodiments of the present invention have been explained in the drawings and described in detail, with varying modifications and alternative embodiments being taught. While the invention has been so shown, described and illustrated, it should be understood by those skilled in the art that equivalent changes in form and detail may be made therein without departing from the true spirit and scope of the invention, and that the scope of the present invention is to be limited only to the claims except as precluded by the prior art. Moreover, the invention as disclosed herein, may be suitably practiced in the absence of the specific elements that are disclosed herein.
