Loki Director Kate Herron Confirms That Loki Is Bisexual in the MCU - E! NEWS

A lot of things about Loki may be a mystery, but his sexuality is no longer one of them.

Sylvie is, as far as we know so far, a lady variant of Loki, known in the comics as Lady Loki.

(She might be someone else entirely, but that's TBD.) She and regular Loki found themselves discussing their romantic lives while they waited out an apocalypse they accidentally found themselves in, and she wondered if, as a prince, Loki had been with "would-be princesses, or perhaps another prince." .

"Real?" Sylvie suggested, and Loki just took a big gulp of his drink. .
