you know, im muslim and you are jewish, but we have the same god and nearly the same rules from this god. ok so this god says that its forbidden to do sex before marriage and its also forbiden to show youself nude in public. we should do what this god says, cause there will be a live after death and this life can be cruel or wonderfull. if u want the wondefull life, u should follow the rules of god. otherwise there will be hellfire
