Dear Lem experts,
I would highly appreciate it if someone kindly gave me a hint on where to find a Lem story I read years ago and simply can't remember in which book of his. It's all about a guy who visits a foreign planet and his friends there invite him to go to the cinema, promising him what we would call an adult or XXX-rated movie. But the only thing the movie actually shows is the extraterrestrians eating, which arouses their sexuality (which is set on a different level than ours) much the same way as watching a porn movie would do to us.
I've always found this idea (imagining alien species with a totally different sex life, i.e. through and by means of bodily parts and processes that are similar to ours, but serve a completely different function) fascinating, and I'd want to employ it in a seminar on the cultural meaning of eating that I am about to give, so I'd really be grateful to anyone able and willing to tell me where in Lem's oeuvre it is to be found.
Regards,
Artur
