hello doctor, I come from Vietnam and I have a question regarding HIV.
my story: I have a habit of masturbating with other people's underwear. So I have stolen panties action (please forgive this stupid job). I brought the panties on and around the penis and masturbate until ejaculation. This at the panties wet (only 2-3 hours after washing) and I doubt they have blood and vaginal washing if no job. So my risk of HIV infection How?
Thank you very much doctor!
