Hi,
The activities you describe would not put you at risk for HIV. HIV is passed when blood and/or body fluids enter into your body through a vein or orifice. Since you describe no oral or penetrative sex, there is no risk for HIV.
Other STIs, such syphilis, herpes, and the human papilloma virus are easily passed through skin-to-skin contact.
It’s difficult to say what’s causing your symptoms, however it is unlikely to be an STI from the massage parlor encounter you describe (as rashes at 2-3 weeks are not consistent with syphilis, herpes, or HPV). Some things to think about: the rashes may be an allergic reaction to oils or products used at the massage parlor, or to perfumes worn by the masseuse. I would recommend going to see a family doctor or walk-in clinic regarding the rashes, especially if they are persisting.
The HIV PCR test is 90% accurate at 12 days, so you can feel pretty sure already that it’s not HIV.
Hope this helps.
