I have sexual fantasies I've never shared... but in not sharing them, could I be, in a sense, part of my own problem? If I do share a fantasy, and other can't/won't meet it... is my unwillingness to let go of the fantasy the cause of my unhappiness... or that my partner is actually reticent?
Well, I mostly believe in Dan Savage's GGG theory so I would say that the unwillingness to share your own fantasies or to be game to try your partner's fantasies (at least in some form or on some level) is the problem. Not sharing your own fantasies reeks of validation neediness and not being open to your partner's is just plain selfish.
