As well as it should. Films should enhance and not degrade.
If one could find a "soft p 0 r n" ( was that Russ Meyer's idea ?)to watch together, I believe it would enhance a sex life between 2 people. Regular p 0 r n is just too crude to do the job right. I believe it should be one on one, not multiple partners. It's a wonder that they all don't have social diseases. I guess some do.
A pleasant love story with some minor nudity would be good to watch together to stimulate a relationship.
