All this means is that you have hsv1. Your number is pretty high, and though it's not an exact science, it's higher than what we'd expect to see early in an infection.
My guess is that this is a well established infection, meaning you've had it for a long time. We can never determine how long someone has been infected just by the blood tests.
It also means that you can't get it again from receiving oral sex. I hope you can let this go now. :)
