It is a long shot, but here it goes.
It is a film from the early 90's or late 80's. I do not know any of the actors or actresses names. I think it is about some scientists who have created a virtual reality machine. The first scene if I recall, is the couple scientists having sex. Another scene is two cowboys and a female prostitute in a wild western setting. The scenes seems to take on a different time for their theme. Other than that there is not much else to go on. It has been bugging me for over a week and I can't seem to find it. Any help would be appreciated. Thanks!
