Imagine a world where men and women have zero risk of any STD, not even a yeast infection. Let's pretend there's no risk of unwanted pregnancy either so everyone can have all the unprotected sex they want. Other than that, everything would be remain the same.

Would this significantly change human sexual behavior? Would we become more like bonobos for whom sex is like a handhake? Would women be willing to lower their standards? From what I can tell, during the free love era everyone's standards were much lower and guys who would be incels today would have an active sex life then. Would guys be less repulsed by high body counts when average guys would also be capable of high body counts? It seems like male pornstars are much less bothered about body count because not even the biggest slut can make them insecure. I think when sex becomes less scarce, men are far less worried about how many miles of dick women take. If this free love movement did continue on past the 1970s, would it have a positive or negative impact on society?
