Dear Dr,
Last night I had a self-masturbation in an airplane bathroom (it was an international flight from China to Australia), and it lasted a few minutes. After finish, I cleaned my penis using the tissues provided in the bathroom. I am not sure if the tissues are clean or not, I am also not sure if someone else (other passengers) had contaminated the tissues, and I cleaned the glans and the penis very hard using the tissues. Now I have the following questions:
1. For my scenario, is there any possibility that I can be infected with HIV?
2. Is there anything I need to do now to stop bad things to possibly happen?
3. Do I need HIV testing?
Thanks very much for your time.
