Like many other animals, human males are just generally seeking to climax (witness a dog's lack of concern for sexual partner), and we know from history that sexual desire for other men is learnable behavior (see Ancient Greece).  Different from other animals, humans were blessed with reason to distinguish between urges that "make sense" and those that don't.  So I'm not all that swayed by the "homosexual" animal argument.

Feelings have proven to be a poor way of selecting a mate.  For thousands of years parents picked their childrens' mates, and with good reason: they know their children, they know marriage, and they know human nature better than their children.  And most married people will tell you that feelings figure very little into how they manage their marriage and their lives.  And, for that matter, sex.  

So all these feelings and desire to engage in sodomy is really rather pointless, especially in light of sexual desire being learnable and love being non-sexual.
