These are surprisingly common examples. The idea behind the first is to redefine sex as a collection of attributes, and then claim that because a significant number of these attributes have changed, then sex has too. So a transwoman who believes this may point to his estrogen levels, breast growth, etc. as an indicator that he is female. This is why many claim to have a menstrual cycle too, it's intended as further indication of being female. When people say that their gender doesn't match their sex, they're expressing a rejection of their material existence. These are men who don't want to be men, and women who don't want to be women. I think it's no surprise that many then engage in self-deception, looking for ways to support a belief that they aren't the sex that they actually are.
