Err... I go away for the day and this discussion seems to have gone backwards!
But, for me to really class you as a woman, this would mean not having a penis and such.
Excuse me, but when was any of this about penises?!
Horny are you seriously suggesting that so long as a man chops his penis off we should all ignore biological FACT, forget all about chromosomes and just accept his demand that we pretend he's a woman?
No way. That's not how this should be working. Chromosomes are chromosomes and fact is fact. You are what you are born and no amount of surgery, hormones, make-up or denial (on all accounts) turns a man in to a woman or a woman into a man.
Be how you want to be. Do with yourself what you want. But continuing with the idea that sex is a choice does nothing but validate damaging gender stereotypes.
