^ Ah, but Donni, the CDs in this thread who say they are not transgender will say they feel no ambiguity with their gender identity as it relates to their birth sex. Hence the issue.
We all can only experience things from our own perspective. For example, since I do not live in my best friend's skin, how can I know without a doubt how she feels about some things? I can only imagine how she might feel by comparing how I feel when faced with the same situation.
I propose that a man who CDs knows no other way of being a male, and therefore he imagines that he feels the same way about his gender identity as any male who does not CD. But, if he were to temporarily inhabit the non-CD's mind and body, he might discover a total revulsion for wearing anything that is feminine. Do both these men have the same male-identity?
Just food for thought.
