Hi Shandar, Nothing you mentioned is a HIV Risk.
Scratching on your hand or fluids from her breast on to your fresh scratch does not put you at HIV Risk.
"No Risk"
Remember, Sexually only Unprotected Anal or Vaginal Sex poses HIV Risk.
One more thing, once exposed to environment the Virus losses its outer shell and become non infectious. So what ever falls on your scratch - Saliva, Breast Fluid/Milk or Vaginal Fluid does not pose any HIV risk to you.
Always use Condoms for Vaginal & Anal Sex and Thats It.
Move On...
