I thought I was stone for a while in that I had issues penetrating another person. I found it upsetting and it turned me off. In my case, though, it was a stopping place on my own journey, rather than the final port of call.
I eventually figured out I was deeply afraid of violating another person, that when I went there, it bothered me because of this fear - to the point where I was dissociating a bit. On top of that, I was just new and I hate being bad at stuff.
Over time and in increments, what part of me I considered stone went away. I am still extremely concerned with knowing boundaries and with trusting my lover to have a strong "no" should she ever need to use it, because I don't want to find out after the fact that something I have done made another person feel violated. It's still a really deep fear. Having confidence and trust in this respect has just really allowed me to be in my own skin and just be able to enjoy (relish) those experiences which I was most reticent about before. Plus, it helps when you're with somebody just really amazing.
Even though I'm not stone anymore, I am really grateful to those stone femmes who were there for me back then. Without several wise stone femme voices, I may have mistakenly felt during that time that maybe I wasn't queer after all or queer enough. I was very recently out of a straight marriage at that time, and I was so unsteady on my feet. The voices and presence of stone people within the community really made me feel like there was a home for me here whether or not I had the capacity or desire to perform to the standards and reciprocity levels that I may have otherwise felt were expected of me.
