Kia Ora Ozma,
I'm an asexual biromantic/affectionate ...No 'sexual' attraction, I just like 'people'... men, women, it doesn't matter... My 'non' sexual orientation came out of the closet along with my gender identity...Just as I believe for many trans-women their true/deeply hidden sexual orientation comes out of the closet with their gender identity...
However I loved my ex - we had children together...I did 'enjoy' sex with her, but didn't 'crave' it...It was just something that couples did-no big deal...
I remember the first doctor I saw about going on HRT, she warned me about the possible loss of 'sex drive', it didn't worry me I had no real interest in sex anyway...
It's possible, if you are 'asexual', after a while feelings will just flow 'naturally' and become the norm ie you'll find contentment...

Meanwhile ...A light hearted look at the difference between natural asexuality and celebacy
. A young monk arrives at the monastery. He is assigned to helping the other monks in copying the old canons and laws by hand. He notices, however, that all of the monks are copying from copies, not from the original manuscript. So, the new monk goes to the head abbot to question this, pointing out that if someone made even a small error in the first copy, it would never be picked up! In fact, that error would be continued in all of the subsequent copies.
The head monk, says, "We have been copying from the copies for centuries, but you make a good point, my son." He goes down into the dark caves underneath the monastery where the original manuscripts are held as archives in a locked vault that hasn't been opened for hundreds of years. Hours go by and nobody sees the old abbot.
So, the young monk gets worried and goes down to look for him. He sees him banging his head against the wall and wailing, "We missed the 'R'! We missed the 'R'!" His forehead is all bloody and bruised and he is crying uncontrollably. The young monk asks the old abbot, "What's wrong, father?" With A choking voice, the old abbot replies, "The word was... CELEB R ATE !!!"

Being asexual is not a 'choice' :
