I didn't want children at all until I hit 30 and something flicked like a switch when I was in a secure, loving long-term relationship and realised that I could love someone properly. (In fact, until then I actively scorned the idea, I thought about getting sterilised.)
Infertility and investigations made me suicidal and almost destroyed my life. Many years on we're living on without them and it's still a source of huge sadness and loss that hits me horribly from time to time.
I'll never get to see my husband holding his child and be a father like he'd absolutely love to be. I'll never get to do the million and one things that mums do with their children. Never give and receive that love, or know that relationship.
I appreciate I'll never know the total exhaustion and miserable, difficult and expensive side of parenthood either, I know, and there's no way to know if I'd have even been any good at it, but I wish I'd had the chance.
And now apparently my entire existence is now justification for making the label "woman" apply to men too - what?!
(Perhaps I should demand to identify as a Mum, cry at you all if you contradict me, buy a fake doll, tell everyone they have to believe I am one anyway, and then lecture you all on how you're all doing it wrong and how everyone believes me. It would be the logical equivalent.)
