Exactly how steamy is this story?
PG
You might think that if your dead ex-wife showed up miraculously, and/or if you were in contact with an alien intelligence who made your secret wishes come true, some steaminess might ensue. But no—all the scientists on Solaris are remarkably chaste in mind and body, and/or Lem just doesn't want to give us the explicit details. Either way, the most we have in the way of sexuality here is men and women lying in bed together and a kiss or two. Solaris just isn't that kind of planet, okay?
