Since you are an obsessive compulsive person, you would remember if you used a condom. You clearly stated previously that your encounter was protected. You used a condom. Nothing else you did was a risk either. Oral sex is not a risk, getting fluid on your penis is not a risk. Air and saliva inactivate the virus. The only risks are to have unprotected/no condom vaginal or anal sex or share IV drug needles.
