Cis male here! I think. Not entirely sure what CIS means.

With the risk of being insensitive, why do people feel that there must be a psychological definition of gender?
Don't get me wrong. I understand that some people are not comfortable with their assigned sex, or that hermaphrodite individuals might feel uncomfortable having to define themselves as either sex, but that doesn't explain why we need emphasize gender as a psychological, like-style option rather than simply what kind of junk you have.
Suggesting that feel more comfortable identifying as gender either than your assigned sex indirectly implies that a gender is more than just a physical aspect - but a life-style, a personality, a fixed archetype that you must belong to or conform to. But isn't that also exactly the kind of outdated, bi-gender society that the transgender movement wants to move away from?
