Electric toothbrush is amazeballs.

That’s frustrating, sorry to hear that.

Important question: are you bleeding from the gums when you floss?

Healthy gums can handle normal flossing without bleeding. I floss once a day, before bed. Normal flossing does not involve super hard scrubbing, just enough force to scrape off stuff stuck between the teeth and dislodge stuck particles. You might also want to add some antiseptic mouthwash to your routine after flossing until your gums stop bleeding.

Gender Critical Feminism is the conceptual framework that gender is a social construct, innate gender identity doesn’t exist, and biological sex is a class that causes oppression of women.

This is actually quite scary that the recommendation is for children as young as 13 years old. Research shows that a lot of gender dysphoria is the result of puberty and medicalizing treatment of it creates a pipeline to further transition including surgeries, while if not treated, the dysphoria often desists after puberty. Growing up is difficult and confusing - how many of us decided we were Absolutely Something as a kid and then shrugged it off later? Something as life-changing as hormone therapy for a physically healthy child should be handled very, very carefully.

ETA: for a thoughtful discussion of these and other topics, I suggest reading Holly Lawford-Smith’s book Gender Critical Feminism (extremely well cited with primary sources) and Helen Joyce’s book Trans.
