I am a long time DL, but recently the idea of my gf wearing a fox tail has become very exciting for me. I brought it up to her and she said it sounded fun. I still haven't exposed my DL side to her. But I realized after I brought up the fox tail to her that I know next to nothing about furries. So could someone give me a primer of sorts. I know that's vague, but I don't really know the proper place to start.
