Human attraction is based around biological indications of someone's ability to procreate and bare the best quality offspring. The reason why men are attracted to women with big boobs, pear shaped asses, and hour glass figures is because they're all signs of fertility and the ability to bare children, and the reason why women are attracted to men with chiseled abs, big biceps and a good looking (symmetrical) face is because they're signs of having good genes and being able to provide for potential offspring.
If we stopped finding other people attractive, we'd still had the biological drive to procreate, it just wouldn't be governed by how attractive we looked. Just like how certain birds decide their breeding mates by the quality of the nests they're able to build, or wildebeest fight over a mate, humans would develop a new way to decide which men and women get to pass down their genes. It might be as simple as having the best personality. Come to thing about it, some men use resources and the promise of financial stability to attract women, so maybe procreation will come down to the amount of resources you have.
TL;DR Yes. Men and women would still procreate even if we they weren't attracted to each other, but there would be new means of deciding factors that would go into who gets to pass down their genes.
