You say they are "disgusting" because you are visualizing what's happening in their bedroom (you must have very vivid imagination or you must have watched tons and tons of gay porn in your spare time). You are not thinking of the simple gestures and expressions of love, the sharing of mundane and quotidian lives, the laughter, and the love and support of friends and family. You must have an extremely perverted and highly sexualized mind to be so fixated on the bodily aspect of a relationship and the bodily functions of two grown men who are evidently very intelligent and highly educated. Who are you? A sexual pervert? A voyeur? People like you are the real disgusting ones - full of bigotry, prejudice, discrimination, narrow-mindedness, and social regression.
