It is entirely possible that a wife continualy disregards and spurns advances from her man until he is engaged in something else he wants to do and then suddenly all she wants is for him to come and "horse around" in bed. Not saying thats whats going on with maximus overlord, but it has happened to me a couple of times.

A woman can get in a funky mood for a week or so where she isn't having it when you want it at all, but she wants you to give something up for it. Like all day and evening your giving her attention and trying to get some and she knows you are trying so she refuses you. Then you give up and that night are watching a really good football game, watching a really good movie, ready to go out with friends, playing a game your into and suddenly now she wants it.
