An alternate theory is that your brain deleted some really nasty, non-sexy images. I shiver thinking about the fellow who edited "Wild at Heart" -- Duwayne Dunham* -- (film editing is a profession I seriously considered.) The film editor, even more than the director, really soaks in the images from a movie.
A few books I really enjoyed on the topic of films & film editing:
When the Shooting Stops ... The Cutting Begins: A Film Editor's Story, by Ralph Rosenblum
Magic Hour: A Life in Movies, by Jack Cardiff
Film Form and the Film Sense, by Sergei Eisenstein -- He was gay, and got in trouble for it, although it was his taste for very young men that finally did it.
All these guys worked on many famous movies and with famous movie stars, especially Cardiff.
* Apparently, he was tough enuf, since he did stuff after that movie.
