In brief: Std checks
The answer is almost always yes.
There are 2 main reasons for this: (1) none of the tests that doctors do for sexually transmitted diseases are 100% accurate; you can miss up to 5-15% of infections. (2) you have to be absolutely certain that your partner has never been exposed, and generally, while you can feel quite confident, if you trust him/her, you cannot be 100% sure.
