As long as there is no sexual tension, I think it is possible for men and women to be just friends. However, if there is no sexual tension then either one or both parties is not at all attractive or they are gay. Being married for forty-seven years, the sexual tension between my wife and me is pretty much a thing of the past. Maybe this explains why we are still best friends. Back in the day, when we were hot to trot, we weren't such good friends all of the time like now. Sometimes, yes we were friends and other times we were more lovers than friends. But then, this is just our experience.
