Vice versa, XX but where the SRY gen is turned on… or there is XYY, XXY, and even XX,XY.
As much as terfs like to pride themselves on being “real”, there is nothing that sets them apart from other women (or whom they incorrectly label as men, or women), aside from being utter asses.
How about spray/gel?
