"How many transmen is menstruation an issue for? If their gender dysphoria is so bad that female bodily functions are upsetting then surely they'd use any of the options available which halt menstruation?"
well actually it is quite common, idk if you are aware of the massive number of pubescent girls coming out as trans. I am as my eldest is one of them. and we can talk about how wrong headed this is and how it's down to social contagion, and they'll grow out of it till the cows come home if you like, but the reality is this is hugely common, and yes, I have been at children's A&E with my kid over their mental health on and off since October, with no sniff of a camhs appointment in sight yet, and my experience is not hugely uncommon. the upshot is that in a world that seems to not give much of a shit about helping my kid with their mental health crisis, this is one thing that I/society at large can do to make their painful existence a bit easier at the minute.
and before everyone jumps on me calling me a bad mother and assuming I'm pumping my kid full of hormones and gleefully 'erasing women' and whatever the fuck else, you can all just pre-emptively go and get fucked ok, because a) no I am not actually and b) I am at my wits' end dealing with this and I am doing whatever the fuck I can to keep my kid feeling ok. I'm absolutely sick of seeing this sneering hostile bullshit everywhere I fucking turn. not all trans people are middle aged men wanking off in suspenders or trying to get their bollocks waxed ffs.
