It's common knowledge that Bruce has been a dating option for Lois in other canons so Clark could see him as a romantic rival before realizing that Batman is heavily involved with Catwoman or something.

The same with Wonder Woman perhaps she (like Mayson) tries to "date" Clark.... But is involved with Steve Trevor.

CLARK: No. I'm just worried I'm a jinx.
JONATHAN: A jinx?
CLARK: Yeah. Let's face it, ever since she's known me, Lois's been kidnapped, frozen, pushed off buildings, almost stabbed, poisoned, buried alive and who knows what else, and it's all because of me.
-"Contact" (You're not her jinx, you're her blessing.)
