DISCLAIMER - Sex/Gender = Same Bloody Thing to me.
But thats not right, and I do not care who's toes I step on. Between sex and gender, synonyms they might be, but not the same. Sex refers to the biological binary of either male or female. There is no in between, outside of birth defects or other biological issues.
Gender is a much for fluid term, at least as far as today goes. You can change your gender just by thinking about it hard enough, as far as tumblr is concerned. Do you see where I’m going with this? It is now possible to absolve yourself of guilt by working enough academic nuance into a word to fundamentally change it — in your favor.
But as long as we are talking about physically changing the way your body fuctions and what sexual reproductive organs you have, the term is "sex".
To answer your question, no. I would not change my sex. I am happy with who I am. Going through some sort of surgery to experience what the other sex feels like for any ephemeral amount of time would
NOT be worth it to me.
