The biggest thing is communication. If you don't talk then you don't know. If she is as naive as you think about BDSM then maybe you could eduacate her on it. Show her this site or others like it. Just don't overwhelm her with it. Start a little at a time. I don't know how familiar you are with this lifestlye but you both might find something new to explore. The biggest thing is to ask her what she wants and also asking yourself what you want and are willing to do. She may have some fantisies she hasn't even dared to express yet because she may feel it isn't right to have those feelings. There are a lot of women out there that have a rape fantisy but are affraid to admit it because they think it isn't normal.And that's just one example. The advice given by Resist and Oz is great as well for introducing this slowly. Personaly i would talk about it before and after the new activities. First find out what she wants then afterward find out if she liked it and if she wants to go further. Doing it first and talking about it after may raise some issues. She may do something she doesn't like only because you told her to and she likes doing what she is told. Does that make sense? If you wait till your done then talk it wont be until then that you find out she didn't like it and only did it because you told her to. Just because you talk first doesn't mean you have to do it right away. It could be days after the fact but at least you will know what she wants ahead of time.
