[QUOTE=Paleobird;1232986]This makes the assumption that one night stands would have been frowned upon. Why would they?
No, I meant it more in the sense that a "one night stand" isn't really a "one night stand" if you know the person. Modern one night stands rely on two unknown people meeting up for nothing but reckless pleasure. From what people who have dated long-term friends have told me, the dynamic is very different when you know someone. Less selfish, no guarantee/assumption it will not continue, no misconceptions about the other (hopefully). Basically, most humans being concerned about others' emotions and the social dynamics of their "tribe" (family or group), we wouldn't place as little value on the other person as is done in a one night stand.
