@TM well then it takes part, TM. If there is no biological things that carried on first, people will not fall in love by attraction only. Some people fall in love because of sex, comfort zone, the safe guarantee, money or even obsession of his crush's /partner's body, face and good looking feature.
The attraction perhaps take a part but the desire to do sex is actually natural things. How about the people who does not have that tendency? Do you think it is based on attraction only?
There is DNA that has been included in our blood, there are chromosomes X and Y that can play a part. So, in my conclusion, even if it is only 10-25% at max, the LGBTQ+ was not created by attraction only. Your statement to Judy is directly pointed to claim that they are doing the attraction meanwhile there are lots of complex combination.
For asexual, it is included in part of queer. You can do googling but this news is actually my reference https://news.temple.edu/news/2021-07-06/why-aromantic-and-asexual-people-belong-lgbtqia-community
