Ok, granted there are obvious answers for this question, such as "to keep warm, protect us from the weather" etc etc. But this question has more to do with the sexuality aspect of it. At what point in time did it become frowned upon to not cover yourself with garments? After all, we are the only species that do this. But why? I'm not looking for a response based in morality, but rather looking for any scientific data or studies on this.
