Aside from that world not lasting very long, I don't think there is anything wrong with sexual desire. My intuition is that the problems in human nature that make many people get bothered by sex are the same problems that drive a chunk of the human condition. If someone was giving me a magic wand I would make those problems, rather than sexual desire disappear.
In reading the scriptures, there are two kinds of mistakes:
One mistake is to cling to the literal text and miss the inner principles.
The second mistake is to recognize the principles but not apply them to your own mind, so that you waste time and just make them into causes of entanglement.
