Gosh yes, babystep, you've dragged up a memory for me to - I think the term used for men's fear of/jealousy of women's ability to reproduce new life was 'womb envy'.
It was a bit woo-ish for me, mother goddess and all that - just not my thing, but all this talk about transwomen 'having periods' is giving the concept of 'womb envy' a new lease of life!
There's a story that's part of Celtic mythology about a queen called Macha [Armagh/Ard Macha is named after her] who was forced by her husband to run a race against a horse [as a result of a bit of boasting, bet nothing can outrun my horse kinda guy-talk] although she was in labour. She won [natch] and then gave birth to twins. She then placed a curse on the warriors of Ulster that for nine generations, they would suffer nine days of incapacitating labour pains every year as punishment, which was a bit of a gift to their enemies in planning when to attack...
So if these TiMs really want to embrace femininity in all its glories, as a Celt I would be only too pleased to channel my legendary ancestor Macha and give them nine days of labour pains ... let's not be stingy, let's #bekind and say every month instead of every year
The labour pains would be in addition to their menstrual cramps of course, we mustn't deny them the full panoply of feminine experiences just because it's biologically impossible.. 😉
