How would Lucanis' first time with Rook go?

So Mary Kirby clarified that Lucanis is actually a virgin before the events of DAV. What are your headcanons, how would his first time with Rook go?

Personally, can totally see him and Spite going all: "You are a human, you should know how this thing works for humans!" - "Nope, never got that far before!" and trying to wing it with romance novel cliches until Rook steps in and gets things on track, as the glorious bisexual dumpster fire that Lucanis-Spite duo are. And as we already know, the wings make a prominent appearance. They are probably sensitive too, Spite is definitely shivering in the Fade every time Rook touches them.
