I once watched a 4 part documentary type show on looking inside a woman while having sex. It brings up what men find attractive about women and why. And it's given me some food for thought.
According to the video, the stereotype of big breasts and big hips are what men look for in women is due to reproduction. Just like how theres an idea going around that women will always want to settle down and have babies because maternal instinct, men look for big breasts and big hips with the thought of fertility. Basically, it meant stronger babies and leads to stronger families/heirs. It even explains why, that big hips are perceived to allow for easier birth (apparently, most people agree on this) with bigger babies and big breasts produce more milk for the child (a lot still think this is true! My grandmother never breast fed her children because she thought with a small set of breasts, she won't produce enough milk. It was when my mother got me and breastfed me, that my grandmother found out how silly that notion is.)
This fertility attraction might have been confused as lust (which, when you think about it with an animal's point of view, it IS lust...), and that's why modern culture now thinks breasts and hips are sexual. I suppose it doesn't help that it DOES in fact feel good to be stimulated in those areas! Marketing is just taking advantage of this attraction, further encouraging the lust effect by producing silly products like push up bras to "make you look fuller" or making it seem like "you can fix your lopsided boobs with this fancy looking sponge and wire combination!".
To me, breasts are... well, breasts. They have a main function that I was born with, to feed babies. They jiggle around because they're soft. It feels good to have them stimulated. The bigger they are, the more annoying. And that's about it. I'm quite neutral about my body parts because I've come to accept it as being me. Honestly, imo, the entire body can be sexual! I mean, I haven't heard of anyone saying "My brain is sexual", eventhough all the sexual signals come from there!
