I think you’re confusing Smallville and Lois & Clark.
Two different shows. Smallville was the one with Clark as a “teen” and never showed the costume. It launched the career of Alison Mack, of NXIVM sex cult fame.
Dean Cain was in Lois & Clark, and wore the costume throughout the show. But he also took a hard right turn afterward while trying to stay relevant.
His weirdly horny Superman refused to put on the costume because he thought he was above it.
Then he stopped being a hero because he didn’t want to help people.
