I love hickeys and bruises in general too, and I am one of those people who turns purple and black and blue pretty easily. Hickies or bruises don't bother me, but if I am going to some kind of special event or need them to be gone for some reason, I use arnica gel. It's comes from a flower, and you can get it in most health stores for about $5 per tube. It really fades my bruises quickly.
Also, I've read (and do this myself because it really works) that the first 24 hours you should apply ice, but then after that, apply heat. Even just running a hot bath or sitting in the shower a bit longer helps. The warm water helps bring fresh blood to the area to wash away the dead blood cells. I hope that helps you!
