"Don Giovanni's seduction of Zerlina is the first time in the opera that we get to see Don Giovanni in full seduction-attack mode." That's how Lorenzo da Ponte's libretto is written. And Don Giovanni ultimately flops with her because at the banquet her new bridegroom Masetto is on the alert, looking out for her. Plus Giovanni's rape/seduction of Anna is off-stage, and it's not quite clear how far he got, although Anna is, of course, quite upset. Elvira's story is from a former seduction; she still loves him, but she's just a notch in his belt, and he's moved on. It's not clear if Giovanni gets to have a go of the maid to whom he sings his aria "Deh vieni alla finestra" as frankly, the opera shows Giovanni on a downward slope with women. He pretty much strikes out the entire opera, at least by his standards.
As I've played/sung both Leporello and Masetto: (spoiler alert since 1787) Giovanni goes to hell, Leporello seeks another master, the Commendatore remains a statue, Ottavio decides he'll wait out Anna's trauma before getting married for at least a year, which leaves Masetto, who just got married to Zerlina, as the only male character who's presumably getting laid at the end of the opera!
