@Cae your correct on faces etc in terms of their uses for telling expressions and recognizing at a distance, however I will say there is something of a facial aesthetic, one reason why for example statues and busts can be atractive to look at, (No doubleentandra intended), , indeed while I wouldn't ever run my hands across a random stranger's face, I like to look at statues, as indeed does my lady.
In terms of appearances turtlepower though, i fully well agree with you. As a stage performer I am very conscious of my own appearance, for all I'll slob around in Pajamas when I'm at home .
Voices can definitely be attractive, but I fully well disagree that "you can't help your voice" as a singer myself I can say you damn well can! help your voice, indeed one singing instructor (a lady who was extremely harsh), said it always surprised her that the two blind people, namely Mrs. Dark and I both had astoundingly good diction, something she attributed to the fact that we took more care over the way we spoke than most people do.
I'm not sure whether this is true or not but I thought it was an interesting idea, and certainly Mrs. Dark and I often discuss the quality of people's voices, both actors, narrators and indeed singers.
Of course physical appearence goes further than that, into realms of smell, presence, posture, quality and type of clothes (something which can be felt), all of which are quite possible to see and manipulate while blind, indeed this is one other aspect where my lady and I are rather similar that when we like to dress up we dress up! .
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
