Thor arches a brow at that question. He thought Constantine was offering him a bed, alone and not to share with him. "You're bold, Constantine. I don't think I will be taking any bedfellows yet... you or anyone else."

It wasn't a hard assumption to come to when John insisted that if Thor desired his time, it would require a price be paid. "I will take a couch."

It's easier to accept than a bed, at least. Too many insinuations come along with that.
