I have been feeling a burning sensation in my penis after I recived oral sex. I got a urine test and it testes negative. I recently did a blood test and I’m still waiting for the results. It’s been a week and it still burns after I pee, and it continues to burn went I’m stitting down or standing up. There are no bumps or miscoloration on my penis, just the burn within. The girl that gave me oral sex said she had no stds at all and she has been tested recently.
