Urgh! I just had a really horrible mental image of someone inventing a gadget so that men can "menstruate" too.
I'm not at all anti-trans but this is just attention-seeking bollocks.
I hate to tell you, but these are already available online. Menstruation kits. Which mimic female menstruation. Involving latex vulvas, etc.
The person in this article isn't just appropriating womanhood, they're fetishising it. Autogynephilia fetishises women's biology.
There are numerous sites devoted to it and films on YouTube involving Tampax up the bum. ( most of them keep their penis).
They are legitimately transwomen according to Stonewall.
Which is part and parcel of the problem with legislation involving men who fetishise women.
The part I haven't encountered quite so much, is the gloating. The transphobes hate this. (I.e. women).
The upfront acknowledgement that it's all about the power.
And yes, of course, genuine transsexuals with gender dysphoria are completely and utterly different.
But both groups are now legitimately transgender.
