Honestly, I wouldn't want to be either! Being a woman is horrible in terms of menstruation- disgusting and painful, feeling pressured by beauty standards (although not any more- screw that) plus the debatable possibility that you will earn less money than men for doing the same job, (I expect that's a controversial opinion...) or be less favoured for a role anyway in case you need to quite to have offspring. (I know that's not supposed to happen but I bet it still does and honestly- I can't really blame employers.)
There again I think men are very pressured these days to be all things. Plus, I have to say the male genital anatomy doesn't really appeal to me either! Looks a bit too unpredictable and messy to me. Think maybe I'm asexual to a certain degree!
Maybe I'll come back as a worm. If I decide I like life, I'll keep splitting into lots of me's. If not, probably won't be long until I'm eaten. Still- looks like worms can live for surprisingly long- 4-8 years. Reckon it would be easier to CTB as a worm though...
