I feel that I'm in a bit of a situation right now. The gal I'm in a relationship with is very strongly interested in submission, and with me in the dominant role. I'm quite fine with that, and even enjoy the notion. However, when it actually comes to practicing such activities, she's very reluctant and resistant. The thought of being submissive is very arousing to her, but she doesn't really seem to want to experiment. As such, our physical relationship is rather vanilla. Anyone experienced similar?
