Might be a spoiler for you, but I kind of explained it for you :)
No, the first time, Felix just revived Giovanni through intimate contact. The blood transfusions that is brought up later in the story is about “curing” Giovanni’s condition by transferring Felix’s blood to Giovanni, since Felix is the only one who can give him warmth.
im so fucking confused theyre talking about blood transfusion but didnt felix already give him his blood when giovanni fell into the river???
