Castiel stopped to think, where would he like to start, and if she had already married, he wondered if sex at this point would be a good idea. There seemed to be some type of rules when it came to this, so he opted to respect those.

"I think sex might be a bit too advanced for me right now, and it seemed like it got me into trouble." He smiled, and he cleared his throat. "And, my observations of my friend's porn collection that's all it seemed to lead to. Not that I don't find sex to be a wonderful thing, but, that is just once single facet of human life."

He continued to think, and he wondered what part of human life he'd love to experience even if it would be very short lived. "What's your favorite part about being human?" It didn't hurt to ask questions.
