hello, a while back I made a stupid mistake by finger penetrating a female "friend of friend" during a drunken gathering. After several minutes, I noticed blood on my hand and fingers. No open cuts or sores I have. I immediately washed my hands in warm soap & water. Are there any risk of contracting HIV in this manner? The woman claims she is clean and had taken an HIV exam and shared the results with me electronically but I wonder if she could have Photoshop her results on the document. My friend tells me I'm paranoid. Can I contract an STI or HIV in this manner?
