Last night my GF really surprised me apparently she has been doing some research on BDSM and wants to start doing the more traditional Dom/Sub thing she mentioned a lot of things punishment and humiliation being what she was mainly talking about I think I can handle this but I am not sure about her. given her spontaneous leap from sensation play to full on BDSM I don't think that she has done as much research as she claims and doesn't know what she is getting into. also when I asked her why she suddenly wanted to make this big leap she avoided the question and when I started asking about her soft limits and hard limits she just said bondage was hard limit and didn't list anymore. this all leads me to believe that she is just doing it to please me obviously my pleasure is a main issue but not the only one from what I have red a successful Dom/Sub relationship should be based on mutual satisfaction and not just the needs of the Dom. I'm not really sure how to approach this situation if I say no and its what she really wants I will feel like a dick but if she is just doing it to please me this could fuck up the great relationship we already have. any advice guys ?
