Yeah, there just wasn't as much textual stuff going on like there is with misogynist dickhead Edwin being turned into a woman and getting dunked on by the women he was rude to. As a cis-man, I don't think I'm in a position to say anything about girdle ogre's gender identity.

Since it's so early in the game, it's a way to teach the player that equipping unidentified magic items can have unintended consequences without negatively impacting their character's combat abilities. Just the "cursed gender belt" bit certainly didn't age well!
