I find that since I've become more active in the forums that my tastes have changed. Although I never did like the skin and bones look, I find more and more that I am less interested in figures and more interested in the personality and especially the level of submissiveness or dominance.
Kate Moss was never high on my list of beauties. Never could find attraction in a woman who was so thin that when I hugged her I could tough my own shoulders (kinda like trying to hug her but ending up hugging myself).
As far as invisibility goes, I think we see what we key in on and ignore the rest, though I suppose there are some who key in on whatever is vertical.
