stay warm, don't walk around bare feet, drink hot ginger and date tea (important)
idk i've done this by accident and i got it early. i recommend all the above, esp. drinking the hot ginger water during period as well bc i get hella cramps and it helps a lot
personally as someone who isn't an 'advocate' but neutral towards it in fiction...
mainly but not exclusively fantasy - wish to be 'violated' but on slightly controlled terms where it's like you enjoy the roughness of getting handled or wtv but you know its safe? no it doesn't, irl rape means not respecting bodily autonomy of others and offenders ......
