I've only ever gotten them off once person! I've never done it to anyone, either. My boyfriend isn't too keen, which is a shame as I liked them. I got horrific love bites of the one guy though, my neck was covered on both sides, it was funny at the time. He always used to tease me and say he'd give me more. My Mum noticed though...

Biting, scratching, oooh yes please!
