"Male||less hot" because if you're in a committed relationship, looks steadily become irrelevant, and hotness takes a lot of work, rarely being natural. Who wants to do that?
Armchair evo-psych explanation for the gender skew is that women would historically suffer worse consequences from abandonment and so have an incentive to find partners with less motive to leave.
Once my later-to-be wife and I walked into the office we both worked at together and the receptionist said “Uh-oh, here come the beautiful people.” Equal hotness is my preference. As Dr House said, “tens marry tens, sixes mary sixes.”
