Super Freak
Large breasts aren't sexual per se. Still you could create an entire argument about the way women are portrayed in media and how they are treated in society in general and you wouldnt be wrong. However, in the end what you are asking for isn't really up to sideshow as they don't control the character designs for these comic book licenses. Superheroes are idealized versions of men and women. Both wear skin tight costumes to highlight their physiques. Why are we offended by women with big breasts and not offended by men with stupidly huge upper bodies?
