As a woman I am not expected to be tough and macho - though if I do occasionally choose to be I get extra kudos for it.
As a woman in a relationship I get to be a nurturing mother, probably the most important role on the planet.
As a woman I am allowed to cry and generally be slushy if want to.
As a woman I can talk about my feelings to my friends without getting funny looks.
As a woman I am more in touch with my feelings and inner self.
As a woman I will probably live longer.
As a woman I rarely have to get dirty changing a tyre on my vehicle. All I do is stand there looking helpless and some kind man get's dirty for me.

As a woman I have a far better sexual responses and enjoyment. (Seriously, the first time I erm... hit the top after SRS it nearly blew my brains out! - I hope that isn't too graphic.)
As a woman my skin is softer and more sensitive, my eyesight is better and under the influence of estrogen my immune system functions better.
As a woman I can wear either female or male attire without anyone questioning me.
I could go on - but this is already way too long a list. I rest my case.
(well you did ask!)
