Told me his story. His attendant ladies also told me their stories. Seems that there's a finite quantity of good sex allotted to each soul each lifetime. After that it becomes a major chore to get to orgasm. Which is why the Ripper started killing girls. Even that didn't help after a while, then he just killed girls out of habit. Why prostitutes? His heart wasn't all bad.
So, with immortality we get a class of immortals, who no matter how ageless their body seems, they have ancient souls and you can see it, no matter the equipment. They lack all enjoyment out of natural sex and do what I do, which is masturbate. Only, the external stimuli involves pain, killing, &etc of the other class of homo sapiens sapiens, which are those who are still mortal. Why? Watch porno for a while and you will understand. Enjoy, Ayn Rand.
