Hmmmm... thats a tough one. A had a similar experience once, though not quite as drastic. Back in high school, I gave a girl a hickey. She played it off to her father as if I was just kidding around and biting her neck. Well, her father than made a comment to one of my friends to the tune of: "Tell him to keep his teeth off of my daughter if he wants to keep them". Naturally, the relationship dissolved not too long after that. I guess this isn't really helping you too much, but I thought I would share that embarrassing story.
