I got these. Just tell them, it’s really a normal issue for us humans and other humans (your parents, doctors) will understand. And! Then you can get some off-the-shelf cream and it’ll help a lot and you’ll feel much better. Go for it and trust that human bodies have bodily “features” and that other humans will understand.
Just a heads up cause I have a furry dog, the roomba or roborock series actually work surprisingly well and help out with the allergens too. Highly recommend trying it out even if for 30 days then return it 😅
I think you’re OK as long as you’re genuine and respectful. It sounds like you’re interested in this character and share your interest in the story with others (so they can be in on your fun too). Go for it, it’s your life :)
Look up PCOS and PMDD. These could be indicators. I am not a doctor or professional.
