Complementary personal lubricant compositions

1. A delivery system for delivering first and second compositions formulated for application to different individuals and to interact with each other upon physical interactions of the individuals with each other, said delivery system comprising:

a first container having a first cap;

a first composition contained in said first container;

a second container having a second cap, said second container and second cap being separable from said first container and first cap;

a second composition contained in said second container;

wherein:

said second first composition, as applied on a first application site on a first individual, is formulated to interact with said first second composition, when said first composition is as applied to on a first second application site on a first second, different individual, and upon contact of said first composition on said first application site with said second composition is applied to a second application site on a second individual, and the application sites are contacted with each other on said second application site; and

said first and second containers are associated with each other by at least one of color, shape, and physical connection to convey to the individuals that said first and second compositions contained respectively in said first and second containers are to be used in conjunction with each other.

2. A delivery system as in claim 1 , wherein said first and second containers have substantially the same shape.

3. A delivery system as in claim 2 , wherein said first and second containers are different colors.

4. A delivery system as in claim 2 , wherein said first and second containers are test-tube shaped vials.

5. A delivery system as in claim 1 , further comprising a holder configured to hold both said first and second containers together.

6. A delivery system as in claim 5 , wherein:

said first and second containers are in the shape of test-tube-shaped vials; and

said holder has first and second container-engaging sites for engaging said first and second containers, respectively, to hold said first and second containers together.

7. A delivery system as in claim 6 , wherein:

said first and second containers each include at least one of a nub and a recess; and

said first and second container-engaging sites of said holder each include at least one of a nub and a recess to interact with the at least one of a nub and a recess provided on each of said first and second containers to secure engagement of said first and second containers in said first and second container-engaging sites, respectively.

8. A delivery system as in claim 5 , wherein said holder is configured to carry said first and second containers such that said holder independently supports said first and second containers.

9. A delivery system for delivering first and second compositions formulated for application to different individuals and to interact with each other upon physical interactions of the individuals with each other, said delivery system comprising:

a first container containing a first composition;

a second container containing a second composition formulated to interact with the first composition when the first and second compositions are applied to application sites on a first and second, individuals, respectively, and the application sites are contacted with each other; and

a holder configured to couple said first and second containers together to convey to the individuals that said first composition and said second composition respectively contained in said first container and said second container are to be used in conjunction with each other;

wherein:

said first composition, as applied on a first application site on a first individual, is formulated to interact chemically with said second composition, as applied on a second application site on a second, different individual, upon contact of said first composition on said first application site with said second composition on said second application site;

said first and second containers are in the form of test-tube-shaped vials each having a separate cap, said vials each having side and bottom walls that are curved such that said vials can be rested on a support surface only in a horizontal orientation on said curved side walls;

said holder comprises first and second container-engaging sites configured (a) to engage said first and second containers, respectively, (b) to permit ready removal of at least one of said first and second containers from a respective container-engaging site for separate use of said first and second containers, and (c) to permit ready re-engagement of said at least one of said first and second containers in said respective container-engaging site; and

said holder includes at least one wall with a substantially flat surface to provide stability when said holder, holding at least one of said first and second containers, is placed on a surface in a horizontal orientation.

10. A delivery system as in claim 9 , wherein said at least one of a nub and a recess in each of said first and second containers and said first and second container-engaging sites of said holder are arranged to orient said first and second containers in a desired orientation with respect to said holder.

11. A delivery system as in claim 9 , wherein said holder is configured to permit storage of said delivery system in a substantially horizontal orientation.

12. A delivery system as in claim 9 , wherein said holder is configured to carry said first and second containers such that said holder independently supports said first and second containers.
