I find the way libido changes with circumstance interesting and almost undocumented, so I write a lot about it here.
During my marriage, living and sleeping with a beautiful (to me anyway) woman who was only inclined to give me orgasms about every second weekend, giving her orgasms about three times a week, my libido was a tremendous drive. And in retrospect nearly torture; I absolutely compare it to the time with the broken neck and the Halo brace screwed into my skull. My thoughts were a constant loop of sex, my wife, frustration. I was strongly tempted to find sex elsewhere, and paying for it didn't sound inherently unappealing. Stereotypically male, more than usual for my age.
After almost a year alone, it has dropped off to about the same level it was between my first and second marriages, which is quite low. Porn that used to do it for me doesn't; I realize I'm looking out of habit rather than desire. I love cuddling and nonsexual physical touch but have no particular desire to take it further. I'm driven to find out if anyone wants me sexually but I do not want anyone that much. I want an emotional relationship, not sex.
So, pretty much stereotypical female desire patterns. I feel like there might be a revelation in there somewhere, but I can't find it.
I am certain that my libido will go back to the way it was once I'm back in a relationship with an attractive woman. For now, it's a big relief.
