Do You Believe the Marriage Bed Is Undefiled?

Let me start by saying that I am straight and also a virgin so I'm not taking a stance on anything or trying to justify an action that I have committed myself. I just want your honest opinion. The bible says that the bed is undefiled, but what about sodomy which includes and ? Since the term gay is not in the bible, the justification that gay is wrong is that they commit sodomy and/or that they can't procreate. If it is the latter, then what does that mean for barren married couples? If your stance is that sodomy is not wrong within marriage, then what about gays that are allowed to marry(I believe 3 states allow this as of now)? Thank You.
