The Danish Girl Steaminess Rating

Exactly how steamy is this story?

R

Einar and Greta have a virtually sexless marriage, but they're okay with that—their marriage is more about friendship than it is about passion. But as Einar explores his Lili side, he visits a club in Paris to watch strippers and people have sex for a live audience. Einar later has an encounter with another patron in the room and gets kicked out. These scenes give the book an R rating.
