Worldwide, every single person stopped enjoying sex. They still get attracted sexually but sex is basically frustrating and feels like it's always uncompleted.
Nobody has orgasm but still ejaculate so reproduction is still achievable.
In a world like this, how is natality affected?
Things to take in account:
- It's basically something just happened from one day to another
- Looks like something hormonal (Incapacity to segregate dopamine, serotonin, endorphin, etc... during sex)
- Everybody is affected the same way
- Only humans are affected
