You can go to any church you want or no church at all.  Christianity isn't about buildings but belief in God, His Son, His Son's work on the Cross and the poker of God to transform a life.  I know these things because God inspired forty different men, over 1,600 years, to record His plan for mankind after the fall of man, to reconcile them to Himself.  Now, to answer your question about gays, if you believe in God, then the answer is in His inspired Word.
