The question comes down to priorities.  Are close human relationships to be only driven by 'functionality', like breeding animals?  Or is the official church unable to recognize that the primary status in marriage/priesthood/consecrated life--- is LOVE first.  Indeed---Love was the primary status that Jesus set, as the cornerstone for ALL of his followers---"Love one another as I have loved you." 
 

The church in the Western world is hemorrhaging members at an alarming rate.  Are today's younger people to be obfuscated by anxieties about sex, while the official church works out its complex and contradictory relationships dealing with gender, sexuality, and the millennial generation?  Young people aren't waiting.  They have lives to live and work to do.
