Hello, eight days ago I received a masturbation service from a Chinese woman at a massage parlor in Barcelona. During the service, she licked my nipples. All the actions involved receiving a hand job and licking my nipples. 1. I'm wondering if this exposed me to STIs, especially HIV and syphilis. I'm really anxious. 2. I'm a little nervous that if she had any bleeding wounds on her hands, could it be transmitted through my urethra, small wounds on my penis, or the foreskin mucosa? 3. Six days after becoming anxious, I went to a clinic and had an STI test, which came back negative. Do you think I need to continue testing for HIV and syphilis? I just want to alleviate my anxiety. Do you think getting tested after 14 days will ease my concerns, or should I wait 45 days?
