While I do appreciate the depth in which you feel things, specifically objects, more specifically plastic phallic objects, I do not understand why you feel the need to lick them in such a manner. While I am perfectly accepting of exploring oneself, I do not see the purpose in tasting oneself. If you happen to be in a lesbian experiment, and you wish to explore the flavors of your new friend, perhaps she would find it more reasonable to go straight to the source.
