That is true when it's specifically guys they're attracted to, but it's not just that, Momo genuinely acts like a sperg when anyone shows romantic affection for anyone. Okarun gets similarly flustered when he's with her, but unlike her, he gives no fucks if a random couple is kissing across the street. I've only seen that behaviour in people who've never had a relationship.
She's, ironically, awfully innocent.
