Well I think kids are wonderfull and love mine to bits. But I know it's not for everyone. My brother for example, gay male who never wants to have his own children, but always wants to 'borrow' my kids for fun outings.
But giving birth I don't think I'd want to do, I mean there's stretch marks, 9months of cramps, swollen ankles and raging hormones.
Hang on, probably a walk in the park compared to transition
