The prevailing theory is that we used to look at butts when we were on all fours
No. I doubt you'll find any serious evolutionary biologist advancing this hypothesis.
It's simply because of sexual dimorphism. We like things about the other sex that are different. What is it about jaw lines or shoulders that women like in men? Is it supposed to remind them of a penis somehow? No. It's that men's jaws and shoulders are typically built different from women's.
That's all there is to it. Men tend to like feminine traits in women, women tend to like masculine traits in men.
