I’m sure condoms also interfere with the fantasy which porn is trying to demonstrate. People’s fantasy don’t involve a condom.
I think condoms also interfere with the “grand finale” which is common to show in pornography.
There was an interesting murder movie from the 80's that featured Melanie Griffith as a porn Star. Body Double. The lead character is an actor who falls in love with the porn star, gets hired for a role in her movie. They have a passionate scene, and the director and producer realize there was no 'grand finale'
Funny and suspenseful. Rated R
