Welcome to comic books... and while you're at it, you might want to check out the SM3 spoiler forum, too. Some really sexist comments in there. I'm a woman and try to overlook a lot of it, but yeah, sometimes it's like trying to change the tide of the ocean with a sand shovel.
Incidentally, this particular statue doesn't really bother me because I see it as an intimate moment between a husband and wife. It's okay for her to act sexy for him when they're at home. (Black Cat is usually depicted even trashier than this. Now that's sexist, IMO. Her entire function in comics is to be a fanboy's wet dream and not much else.)
