If you can only get an STD from someone who already has one then how did STDs start in the first place?
Excellent question! They started just as ordinary ilnesses started: as harmless microorganisms that changed into a more harmful kind. Some "jumped" from animals, others lived in the human body already. Since microorganisms are so small, incredible numbers of them can inhabit a single person. Every time one of them multiplies there is a tiny chance that damage to its genes will result in a new kind of organism, and due to the vast number of them it happens quite often -through blind chance alone I hope this helped, good luck
