Then go back to your doctor and work with your OCD. You have no reason to test. You are beyond the scope of help that anyone on this forum can give.
Are you sure? I have been tested about 15 times over the last 5 years. I do suffer from the whole HIV OCD thing, and everytime I have sex something stupid like this happens and freaks me out. Well, I still will get tested I am sure, just to put my OCD at rest, but the reassurance is good. I get scared of the blood thing.
No you don't need testing. You had protected sex.
