You remember your firsts, especially where romance is concerned. First love. First kiss. First true sexual encounter. You remember them usually because you didn’t really know what they were till they happened. They open up a rush of new thoughts and sensations, like you’ve stumbled on a world you hadn’t believed in till you found yourself in it. The feelings that come with that new world may be the beginning of a long sequence that eventually becomes familiar and staid, but they begin as surprise.
