How long does it take for STDs to show up?
Depending on the specific pathogen (disease-causing organism) symptoms of STD may appear within four to five days — or four to five weeks. Some infections might yield noticeable symptoms even months after the initial infection.
STDs arent transmitted every time you have sex, but they can be transmitted any time you have sex. You can get an STD the first time you have sex. But there are no STDs that will always be transmitted every time someone has sex.
