Of course they can, although it is unusual. But you did not make any point with your sarcasm other than admitting you didn't understand mine.
The culture should not accept any sexual behavior as "normative" outside of a monagomous homosexual marriage.
Shalom.
So then, what exactly is so magical about the act of marriage that sexual behavior inside of marriage should be considered "normal" and outside of it "abnormal"?
Surely you have much a different definition of "normal" and "unusual" then the overwhelming majority of Americans and, I'm quite certain, Freepers.
Or maybe you should get out more.
