I read a story about a person who had a sex change 3 times, someone asked how will they know who they are. I thought to myself if I did not know my Gender or the existence of such a label, would I still know me, know myself and the answer is a clear certain yes. My consciousness, thoughts, my core me has no gender tied to it, it simply is. I Simply Exist and would still know me even if I had say a thousand sex changes, such as reincarnation perhaps.
