My question if the vaginal fluid is Mixed with oil massage and exposed to my fresh urethra scratch do this increase my risk
Theres no need to test for a handjob as its not a way to get infected with hiv,having unprotected penetration sex is a risk.
No point testing for that non risk event as it will come back negative for sure.
You have no risk from what you've described, even with this scratch that you keep going on about. In an adult, only unprotected anal or vaginal sex and sharing IV drug needles are possible risks for HIV. Nothing else you can think of is a risk, including everything you've posted here about the scratch and everything. No risk means obviously nothing to test.
