I have a boyfriend I've been going out with for a year or two, I don't know how long because I don't pay attention to that kinda shit, but he has this big sloppy friend named Bryan that I enjoy sex with frequently. I recently confronted my boyfriend about a homosexual relationship he had with a dog. He flipped out and called me a whore so I persuaded him to let me go down on him and then I bit him in the dick and drew blood. Skin stuck to my teeth. Unforgivable?
