My girlfriend is my buster and she really gets into it. When she tells me that when I tell her to stop, she will continue because it's what she knows I want...and she also really enjoys it.

I had not thought of it as liberating, although it is in a sense. It allows me to fall in to the experience knowing that I will feel it. I enjoy not having the control, which I think is similar to you being told it's ok to cry.
