Would be funny if Nina found a way to get her sister´s body for herself
makes no sense if he is now into girls why is he trying to seduce his former male body?
Either he's just teasing or he's into himself (narcissistic). Wouldn't you like doing yourself?
Yeah he's just teasing her. He doesn't really want to sleep with her. Plus, he doesn't actually know if he's still into girls. He just believe he does :)
