If you didn't show symptoms by now, no reason to continue worrying. Hsv1 genitally tends to present with pretty classic and obvious symptoms that you wouldn't miss.
No reason to wait for blood testing just to see what your general status is if you are interested.
The general rule of thumb is, if your clothing is off, a condom should be worn. It protects you, saves you worrying as well as saves you from frequent testing for std's. Even though the risk of a std in general from oral sex is pretty low, it's certainly not zero and a condom for oral, both giving and receiving, is always in your best interest
