I ran into a fun thing back in the early 60's while stationed in Japan. There were old men who would travel around with a film projector and an assortment of stag films. For a small payment at a group get together he would provide an evenings fun and entertainment. One of the guys I worked with was married to a local lady and they and some of her family would all gather with us for some movies. All of the films were local and very funny besides being sexy.
A few years later while in Vietnam we got a hold of some films that came from the UK. They were good. Like the Japanese ones and the local ones I saw years ago up here, they featured "everyday" men and women and were more "real". Of course there was not any sound so we didn't get treated to all the howling and carrying on like most of the current videos.
Just remembered one I saw while visiting a friend at OU in his dorm. This one was French and turned out to be a bi film. It had 2 guys and a girl. While one of the guys was licking the girl, the other guy started sucking the guy. And they went on to do all kinds of arrangements. It was a real surprise to see in that part of the country, in the 60's.
