On people who dream about being the other sex (also called "autogynephilia" and "autoandrophilia")
A portal for crossdreaming and "autogynephilia"
There are men who dream about being women and women who dream about being men, and who express this longing through feminization fantasies and/or crossdressing.
I have started a blog for and about men and women who live between the genders, called Crossdreamers. This portal is set up in support of that blog.
Please note that the terms "autogynephilia" and "autoandrophilia" are both misleading and offensive. I am including it here, as I know people search for the term when trying to understand what crossdreaming is all about.
