Allah's(God)'s Prophets don't make their own religious laws, they are born with good morals values from birth. Every prophets told to mankind not to be, that you should not be. Either appear as you are, or be as you appear. Don't appear what you are not. Don't do, what the society doesn't want you to be appear. Animals don't appear different then they are, are they? Why humans, want to appear be, what they are not? If God want humans to screw both genders, we would all have both sex organs.
