Hi Boots.  In the Jewish faith there is a Biblical basis of the prohibition against homosexual acts.  There isn't a prohibition against being inclined to homosexuality as long as one does not act on that inclination.  The prohibition derives from two biblical verses I believe, Leviticus 18:22 and Leviticus 20:13.  The Jewish ideal family is a happy marriage and lots of children.  The notion of a marriage not being between a man and a woman would have been entirely alien to rabbis of the past - likely so alien that it never crossed their minds.  Finally, I suspect Christians share the same Biblical verses I cited.  As for Muslims, I'm not sure which teachings they cite in this regard.
