It's really worrying me that Dean(writers) so concern about Cas's sexlife. I mean, what they want to get? Cas lay with a human when he is an angel and become even more fallen than he is now? and never get a permission to see his home again and fix his self guilt problem?Does Dean want to make him a human? To bind him to them? Do not let him leave them? Or even worse? to let Cas and his new girl give a birth to Nephilim and start a happy "let's try to survive from furious relatives" family?
