Okay thanks for the response! I will wait a lot longer now :D
Anytime you see blood something is wrong. You need to leave it alone for a while, more than a week. Think of it this way. When blood is flowing it is red. As it dries and becomes wet to flow it is brown. You were right to see a doctor, but you should have been more honest and ask how long until you could Masturbate again or have sex. He would have told you to wait for a few weeks of it to completely heal and you never would have seen any brown tint.
