“Would an example of sexual selection be a man who looks like Usain Bolt preferring a woman who looks like Veronica Campbell Brown, and creating more children who can run like….lightning bolts?” 
More an example of assortative mating.

Assortative mating based on female preferences is more restrictive, because the resulting sexual selection can lead to loss of the trait polymorphism and cause the relative fitness of heterozygotes to rise above homozygotes, eliminating the force favoring assortment.

The same seems to be true with high intelligence. It tends to create reproductively isolated groups.
