[Titus Templeton]

Genesis 19:24 Then the LORD rained upon Sodom and upon Gomorrah brimstone and fire from the LORD out of heaven;
Genesis 19:25 And he overthrew those cities, and all the plain, and all the inhabitants of the cities, and that which grew upon the ground.

When God created men He implemented a double firewall security to make sure Gay Anal Sex won't have a chance. We call it the internal anal sphincter and the external anal sphincter.

Leviticus 18:22 Thou shalt not lie with mankind, as with womankind: it is abomination.

Leviticus 20:13 If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them.

The internal sphincter is involuntary (which means you do not control it but God can close and open it but it's closed by default) while the external sphincter is voluntary. This means you have control over it and you are responsible for it.

Deuteronomy 23:17 There shall be no whore of the daughters of Israel, nor a sodomite of the sons of Israel.

So the internal sphincter is almost always contracted by default (this serves an important role in continence of liquid and gas), but if you fear something it can cause it to relax (why you may sometimes feel the need to go to the bathroom when stressed or nervous. Also why people may soil themselves in scary or stressful situations).

1st Kings 14:24 And there were also sodomites in the land: and they did according to all the abominations of the nations which the LORD cast out before the children of Israel.

Because of this, it's fairly unlikely someone's "inside butthole" would pucker for most reasons. This is the reason why Gay Anal Sex is often so painfull. Even if the gay deactivates the outside sphincter that he has control of God will still keep the other one shut down. But the more Gay Sex a person has the more the closed sphincter looses it's strenght. Too much penetration over time will simply destroy the inside sphincter. Because of this most gay people have to wear diapers.

Deuteronomy 22:5 The woman shall not wear that which pertaineth unto a man, neither shall a man put on a woman's garment: for all that do so are abomination unto the LORD thy God.

So the Internal Anal Sphincter and External Anal Sphincter are not only proof God is real it also shows God does not want Gay Anal Sex to happen.
