@branman65 SuperSnekFriend once pointed out to me that, when Adam was lonely, God simply created a wife for him. So, from the beginning of man kind, God thought it was good for us to have a companion!

And, if there need be, God can just create a wife for us xD

Honestly, I think one of the reasons Paul stopped caring about having a wife or family here on the Earth, was because he saw, that people had a better form of a wife and family in Heaven. He could see that he was missing out on nothing, but wasn't allowed to talk about it xD
