Hello doctor, I went to massage parlour which is a decent professional massage centre. In the course of massage at the end, I insisted the massage girl give a hand job but she denied. After that, she gave me a brief hand job for 60 seconds. And occasionally she holds my penis very tightly and pulled tightly twice and rubbed my penis shaft twice each for 10 seconds. She touched the precum twice. In the end, I myself given a hand job and finished it. After that I checked my penis and my hands there is no visible blood. Also after cleaning and bathing (after 15 mins) I checked the massage girl hands there are no visible cuts. What if she had pin size cut and a few drops of blood bleed on my penis while she masturbates me is there a risk for hiv?
