You can only get an STI by being in contact with the bodily fluids (blood, semen, etc) of an infected person, either through direct -blam!- contact, or by other means (ie, infected needles, blood transfusions).
They made this pretty clear in sex-ed.
If you stuck your hand up an infected lady's vajayjay, then started fapping, you'll probably get one.
How do you know ur infected? How do you become infected
