Cunnilingus After Razor Burn

I have for years tried to figure out how a heterosexual man could get AIDS. I believe they shave with a straight razor, have razor burn, and causes the blood to come to surface, but not really bleed. This is how the face is open to blood.

They then give face to girl vagina. Cunnilingus.

Bottom line boys, I think you need to shave in the early morning, and not right before you go over to your girls house.
