I will address the offending issue first and close with a direct response to this thread.
I don’t believe that disclosure of gender variance rises to the level of a moral obligation but I think it is a good policy to do it in relationships that might be seriously harmed by nondisclosure. Everyone has sex, gender, and sexual preferences for themselves and for their intimate partners. If your potential partners prefer to have a relationship with a masculine heterosexual male and you know that you are not such a person in significant ways then perhaps it isn’t wise to keep this a secret from them. On the other hand, there is really no harm done when you don’t announce your raging queerness to strangers on the street. Most of them probably don’t want to marry or move in with you for other reasons. It’s not a bad policy to limit your disclosure with them. So voluntary honesty is the best policy in some cases but not in others. Regarding the issue of gender variance there are no higher imperatives to consider.
