Respectfully, I'll have to disagree with this statement. I don't know you JCFantasy23 and I don't know your background but I really do feel sorry for you if sex has become such a mundane thing to you that you feel it should be discussed as one would discuss the weather or the news.
While I do believe that sex belongs in marriage and that there is something "sacred" about it from a Christian perspective, my argument with regards to your statement even comes from outside of my religious conviction.
Between a couple, the most intimate thing you can get involved in on a physical level, is sex. That is the top rung of the ladder, there's nothing more intimate. Putting that on the level of the weather or the news makes something which is very intimate into something very base.
While sex is a physically intimate thing, I could use the emotional analogy of discussing the death of one's father. That's an emotional intimate thing to discuss and I would never expect that someone should be able to discuss that with the same ease as the weather or the news.
For what its worth, I also believe sex to be more than just an intimate physical action but also a very emotional action but maybe that's just me.
