I haven't asked her if she has any diseases because I didn't think I would be at much risk from just massaging. I purposefully did not kiss or have sex or any oral contact with her because I am rather paranoid about diseases... so I think I did good on that respect.
I suppose that even if I did ask her, she might be unaware of having a disease or she could even lie about it. I have known her for 2 months and trust her so far.
You are right, I want to avoid infection but I guess there's always a risk no matter what. Unless I never touch a woman again. What kind of life would that be like? Ugh.
