How Should my shapeshifer mate with a psychic?

So, I am writing my book like crazy this week and making some real progress when I start thinking ahead to some of world building issues. I found this great place called the Tail of the Dragon in North Carolina that has really inspired some of my work and now have moved on to some rules for my species. What do they have to do to make their mating official. It cant be ordinary or too complicated so I have been tossing around some different ideas. At this point I have decided that my heroine would have a birthmark on her neck that my hero would have to bite while they were making love. Probably right at the time of climax. I was trying to avoid the whole biting thing but haven’t come up with any alternatives yet.

My next topic is what do I call my group of shapeshifters. I would love to have a quirky sexy name for them. No ideas yet but it is definitely on my mind.
