So basically, my partner's mom asked if I were transgender. I'm not, but my partner doesn't understand my gender identity or even what gender is and so answered that I'm bisexual. Which is true, but answers the question in an offensive way.

I'm not comfortable having someone (regardless of relationship) outing me without my knowledge or permission. Now, I'm sure I've disclosed information on people that in hindsight I probably didn't have a right to, but there's something about sexuality that should be more confidential than other things.

And then, answering a question on gender by defining sexuality. That's what I'm most offended by. If you don't understand gender, then just say you don't understand enough to adequately answer the question.

I just don't know how to approach this. I feel violated I guess, but I'm not sure if it's justified or not.
