HSV 1/2 I just need answers plz.

A girl gave me oral about 2 months ago. two days after the oral i felt a stinging pain on the tip of my penis that will come and go. it lasted about a week. There was some Swelling and redness on the tip of my penis. i went to get tested for all std about a month after my Experience n came back negative for everything. I have a gut feeling this is herpes....

... do you have a rash or blisters? 

you can test for herpes via a blood test to confirm. 

i dont have any bilsters, i might have had a rash. The oral only lasted about a min or less. I took a hsv 1/2 blood test a month after the encounter and it came back negative.
