People don't like to admit to being shy because, much like submission, its often categorized, or at least they are worried it will be perceived, as being weak. Also people often equate being introverted as being shy or embarrassed because we live in an exhibitionist society that idolizes loud/brash/pushy extroverts as the most desirable model (though paradoxically such behavior often hides the biggest insecurities). Some people however just like to keep certain things private, special.
For a while I entertained putting my vanilla pic here just so you could enjoy my pocket size venus looks,. Lol.
All jokes aside, being happily committed I don't have the need nor the desire to attract anyone, but I always wanted to know what people truly think about me and why they react to the way I look the way they do. We did a similar experiment at the psychology class, it was a demonstration about how quickly we "box" people up. Professor showed us two face portraits and asked us to write a short opinion essay about what our conclusion is of those people, with no additional information, just by looking at their faces. I always wondered what if it had been my picture; and if I ask face-to-face I never believe the answer I get to be complete/honest/unbiased.
I discarded it for two reasons: one, I really, really, really, truly HATE having my picture taken (maybe one ever 2-3 years and thats when I absolutely cant say no); and two, to do that my Dom/husband would have to agree and lets just say he is of the type that likes certain things to be for His eyes only. (And I like it that he likes it that way.)
As to the original thread question why don't Doms post pics of themselves? My theory is that they are shy, lazy and some of them are just embarrassed of their pot bellies,.
And Tom, you do have really nice eyebrows,.
