Excellently and concisely put Dalebert!
I agree that's it very much based on personal preferences as to whether a person feels dis-enfranchised or under-privileged due to their gender. Each gender carries its own responsibilities and perks. Currently society decides which you receive based on your biological sex, but it would be wonderful if you yourself could also have a profound say on your preferred gender based on what going to help you thrive and become as productive & positive as a human as possible.
For myself, I'd definitely prefer to be female as the way I want to dress and act, to feel and the jobs I want to do are far more expected and suited to females than to males, both socially and also biologically. Once again, this of course depends on one's view as to what's expected of genders.
Personally, I'm irked about my body. As I'm petite (size UK 6-8) in women's clothes, I look terrible in male-cut clothes, but quite nice in ladies' clothes. However my cunky veins and hairy skin kind of ruin that, so I'm forever looking awkward and ugly in whatever I wear.
