everyone who has posted ahead of me i think has covered everything. as for me, i'm completely new to this lifestyle, so the image that pops into my head is just an Average Joe the Plumber. i feel that looks, regardless of the individual being a 'master' or not, aren't important if he has the charisma and the ability to keep a decent conversation going (i.e. personality) to make his appearance mean little. however, if my future Master is as beautiful on the outside as he is on the inside, then i say 'bravo!'
*pardon the cheesiness of the ^^ above sentence*
