Yesterday, i rode bicycle with my classmate, my arm was scratched by his nails and there was a scar a few centimeters. at the same time had a small amount of bleeding. I observed slight redness in his fingers, which should be barbs. He is my classmate, and he is not gay.
I was very nervous because I was afraid that the cut on his hand would come into contact with mine and there would be a risk of infection.Especially i search internet, blood is the main transmission route, which makes me very panicked. I have a phobia.Do I need to do anything?
