"I have been going back and forth on weather love must be conditional or unconditional. I have just read a christian article on marriage and I am leaning towards UNCONDITIONAL."
Then you said this:
"She must also meet his uncondtionally, which means she must desire sex with him UNCONDTIONALLY."
By saying something must happen in order for love to be there, you are setting a condition. The natural logical counterpoint is that if "she" does not desire sex unconditionally (a rather bizzare concept by the way), then he is free not to love her unconditionally.
Of course, there are several other logical fallacies in there, but its too early in the morning to think about them.
As far as someone desiring sex unconditionally, can you see how absolutely crazy that is? For one, that would be completely dishonest, we all wax and wane in our desires from time to time. Two, it would be a license for the people to not put ANY effort into the R, i.e. "you have to want me, so I don't need to do anything to entice you." For one, the concept that someone MUST want something is silly. For two, that would be an awful relationship. God, my head is spinning with all the logical and emotional fallacies that I could come up with for that. I'd better stop.
