What Is The Risk Of STI Or HIV From An Oil Body Massage With Hand Job, Including Contact With An Unbroken Acne Boil?

Hello Doctors What is the possibility of infection when the only sexual exposure was oil body massage with a hand job. There was no oral, vaginal or anal sex. I briefly massaged the lady breasts and kissed her neck. No lip to lip kissing 1. I had a acne boil on my back due to sweating in summer. The acne is intact and not broken Does the fact that the lady massaged with oil over the acne pose any sti/hiv risk 2. I assume they do not change the sheet, in such a case can there be an infection from the supposed fluids of the previous customer. I think the previous client was sometime ago as there was no one when I went in. Please help address my concer
