I will try and answer ( I hope that is ok @YouAreNotBatman - I am jumping on your thread)
AS a child and teen, growing up, I didn't understand the hopes and dreams of my friends, or the expectations of my family
This is because it was mostly based on marriage/ long term partnerships
This was presented as so normal, that I can remember not even being able to find the words to ask my (loving, caring) parents why people seemed to be orientated towards this, and I was not - the first conversation I had was aged about 6, when I tried to ask my Dad where I would live if I didn't marry, as I only knew family or couple households - his response was to reassure me that I would probably marry/ have a long term partner
I grew up not knowing asexuality existed, or that I was asexual
I assumed I was gay or straight, and if I wanted a home and family, I had to learn to be in relationships
I tried and tried and tried
Multiple engagements, multiple financial entanglements, multiple broken hearts (other people's not mine) when I just couldn't follow through
The portrayal of asexuals in literature is very unpleasant, I came across several who were psychopathic, for example, and in the end thought that must be my problem
So, ignorance of asexuality lead to many wasted years, many hurt people, much wasted money, and a "secret" that I dare not tell, that there is something deeply wrong with me, I am probably a very dangerous person
The day I heard that asexuality existed, everything became clear!
There was an article on the BBC - several of my best and oldest friends contacted me the same day very excited, saying they had seen it, and recognised me in it
So I know I am normal, and have based my life choices on being asexual, and single forever, and have a very happy life, fostered, worked towards a single person's mortgage etc
Some asexuals may choose differently, and go about looking for a celibate marriage, to raise children in, or whatever suits them
But you have to recognise what you are, to base your planning and future on.
I tried SO HARD to be straight, because I thought it was just a matter of trying harder and harder, and I would eventually get it
So yes, I think it is very important that asexuality is recognised, on equal opportunity forms, for example - otherwise it is just saying we don't exist, and we do - and as you can see from this thread, lots of people think we don't exist. And that creates chaos in people's lives.
Incidentally, I also chose to be a single Mum, my hormones are normal!
Asexuality is completely different to a sexual person having a medical issue which causes problems with low libido.
