Male animals much better looking than their female counterparts

Scottish MP's.

which one turns you on aka ?

peacock

pretty much like pheasants, and male likes to show off his expandable
tail

Don’t we all.

Well seen what floats Donnys boat

Lion (NAP)

Me.

But don't tell my female counterpart.

Blackbirds.  The chap is pure black with an orange beak.  Very smart.  The lady is a drab brown.

Birds of Paradise the epitome of this, female rather drab so as to be more inconspicuous on the nest whilst the males strut around like Carnaby Street in the 60's

https://en.wikipedia.org/wiki/Biological_ornament
"Male animals are typically more elaborately ornamented than females.[19] The classic sexual selection theory notes that because sperm are cheaper to produce than eggs, and because males generally compete more intensely for reproductive opportunities and invest less in parental care than females, males can obtain greater fitness benefits from mating multiple times.[20] Therefore, sexual selection typically results in male-biased sex differences in secondary sexual characteristics, which are non-reproductive body parts that help distinguish between sexes in a species.[20]"
