You first skydive is tandem - you're strapped to an expert who knows what to do. He (or she) does all the work, and you just enjoy the ride. Exiting the plane is a bit nerve wracking, but your point about having no frame of reference is totally right. You just feel like you're hanging out in the sky for a while.
Then again, I'm not really afraid of heights
