Go for it. I would love to know how a person that has no desire can actually genuinely change this.
Myself, I ALWAYS desire sex. I still desire it with my wife (even when I probably should not). SO I have no experience ever with lack of desire. I read about people where it comes and goes, or they can turn it off, and I have absolutely no way of comprehending this. People claim to go for days without even THINKING about sex, and I can not go for 1 hour without thinking about it.
