Based on historical trends, it would seem that society becomes more and more open about sexuality, and espouses new ideas each generation. Based on this progressionist attitude, can we assume that eventually we'll all be basically just walking about nude like so many nudist colonies, and practicing intimacies right out in the open? I'm looking for futuristic insights into what our society's eventuality will be in relation to human sexuality. I see the possibility over time of 2 person marriages possibly giving way to multi-person marriages, or maybe even complete lack of marriage at all. What do you guys think?
