What happened to the ten commandments?

I saw something about christian swingers online and i just made me angry. Then i lnow some people who caude in bible times, men had several wives and heroms, and the wives would pleasure each other when the man wouldnt. And girl/girl doesnt count as adultery. And i know some people who are "born again christians" who are priud of some of their thefts. Does noone fear god anymore?
