Hello, about 10 days ago I received oral sex from a transsexual prostitute, who I believe is high risk ( she was very cheap). She admitted she is a drug user but is clean. She also had recently relocated from Atlanta which is a known for a high percentage of hiv positive people. I did not notice any bumps or cuts on her lips or gums. The oral encounter lasted about 2 to 3 minutes. That was the only sexual encounter, is their a legit possibility to have acquired hiv from her? Thank you.
