alt Hacker News> I fear that we have a risk budget, so when STD risk is reduced via a cure or prophylaxis, humans increase the amount of sex they have until the STD rate stabilizes again.
Nope.
Gen Z rather famously is not having a lot of sex despite all the scary STDs not being as scary as they’ve been historically.
Granted they also do less alcohol and drugs I hear. But it's still very early in that cohort's life, and there's also going to be other next cohorts.
The expected timespan for the benefit of this cure to dissipate would be in the decades.
