Why are women obsessed with their thighs?

Us females we love our legs sometimes when we have nice legs we love to show them off because that might be the only proud things we love about our body. Or we love to move and everything with our legs. So showing off our legs and thighs are just natural to us it's just how we are built to do. We also know it makes guys turn into jelly so that's another reason to haha:6
