Query: This is an odd book...

The author claims that sex is ok but lust is the problem, basically saying that sex is tolerated by god as a mechanical function for procreation, but if you enjoy it then he gets mad. The author seems to think of god as being like the incredible hulk. God gets mad and turns into a rage filled monster when people enjoy sex or affection.
