>>106195918The DCAU episode "The Great Brain Robbery" implies that Lex Luthor is a selfish lover.
The Batman Brave and the Bold episode "The Mask of Matches Malone" has Huntress, Catwoman, and Black Canary criticize The Flash's sexual stamina, Green Arrow's technique (though the line could also be interpreted to question his sexual orientation), and Aquaman's penis size... though this is performative so there's no guarantee they're serious.
