Vayikra 20:13 forbids anal intercourse according to Rashi who describes the offense as "inserting a paint stick in a tube." Since non-Jews are not generally subject to laws asur mi'd'rabbanin, no fence should forbid them from approaching this prohibition as long as they don't commit the offence itself. True? So shouldn't non-Jewish males be allowed to show affection to one another and even to have sexual contact together as long as they don't commit sodomy? I know the idea may be repulsive to many Jews, yet isn't this halachikly correct?
