A lot of supplements and body care products will claim that they need to know your gender because they have ~special formulations~ for the ~unique needs~ of men and women, even though these are often inaccurate proxies for the actual factor being described
But this raises the very real possibility that in 15 years' time rainbow capitalism will produce multivitamins, probiotics, skin creams, etc. labeled with shit like "formulated for diverse masculine bodies" by which they mean "trans people on testosterone who possibly menstruate" and we'll just have to live with that
