That is essentially what this does.

But nobody's suggesting we use these words to introduce ourselves.

It's no different to me pointing across the room to say "That's Kizzy, the tall brunette lady!". You are a woman, in a relevant conversation about sex and sexuality you would be a "cis woman", just as you would be a "straight woman".
