We do not believe that it can be seriously disputed (and C.T. does not) that Hoosier society, in general, considers the female breast to be an erogenous zone but does not consider the male breast to be one: public display of the former is almost certain to cause offense and unease while public display of the latter is not. Just as “[t]he Constitution surely does not require a State to pretend that demonstrable differences between men and women do not really exist[,]” we will not pretend that female and male breasts are thought of in exactly the same way in contemporary Indiana society . . .
We conclude that Indiana‟s public nudity statute furthers the goal of protecting the moral sensibilities of that substantial portion of Hoosiers who do not wish to be exposed to erogenous zones in public.To the clueless, the word "erogenous" means "sensitive to sexual stimulation." C'mon, Judge Bradford, tell me you've never played with your nipples during a private moment of self-pleasure or allowed your spouse to arouse you by playing with them.
