Something's been puzzling me for a while now, but became particularly obvious whilst watching the magnificent Game of Thrones.  There's a fair amount of female nudity in it but all the actresses are very small breasted.  Nothing against small breasts, I've always wanted a pair myself but it begged the question.  When does female nudity cross over from art to porn?  Surely it isn't a matter of breast size.  I've noticed it on a lot of film and TV.  Are our breasts less offensive if they are less 'in your face'?  Can they get away with more naked breasts because they wrongly assume the smaller they are, the less we notice them?
