Yay! That's awesome. It sounds like you are too. Isn't this your first device? =P That's great though because you two can experience it together and learn how you'd like it to work in your relationship as you go. If you are going the it's completely up to her route I'd set up a time each week to discuss how things are going and don't mention how you feel about being locked up outside of that scheduled window. That way your not always bringing it up and trying to give her hints. Let her have time to figure it out for herself without you helping her. =P I think you are overthinking this. Calm down lol. Seriously don't give her a list of do's and don't's. I'd actually recommend you avoid giving her any sort of guides or user manuals. I know your probably super excited and ready for her to start doing all the kinky stuff you've seen online like yesterday. But I promise you she will have a blast learning how to be a key holder her own way and in her own time. It could take that experience away from her if you get impatient with her and start giving her homework on how to hold your key correctly. In my experience not pushing her is probably one of the best and maybe most difficult to accomplish peace of advice I can give you. She will figure those out pretty fast. General you'll be horney, frustrated, constantly thinking about sex, and possibly annoyingly touchie feely. You'll wake her up in the middle of the night and you'll probably have mood swings. Basically you'll be on an emotional roller-coaster until you get used to constantly being sexual frustrated. Sounds fun right? =P We got a knock off holy trainer for like $30 online that has worked good for the last 6 months. We ordered a metal one for $20 but it hasn't got here yet.
