At the least, once a year.
This can vary between people with certain partners and such. You should test before symptoms appear because usually, once symptoms appear, it is too late to be cured or treated.
Every six months can be frequented and sometimes preferred but is not required. Once a year is the least a person could do to test for STD's.
Hope this helps!

That’s kinda hard because drugs can help you sometimes especially when it’s subscribed to you but then you can also get cooked on medicine like pain killers.
