Hello @zararina :)
Thank you for taking the time to read and leave a comment. I am pleased to hear you find this topic interesting. Me too! And, as well as you, I also think it is complex. Not only in itself, but also in how it is perceived by others.
In this article, it gives more possible causes and insights about how could one determine his/her real sexuality.
It is great to see that is how you see this post! There are a lot of explanations out there, many different way to try to make sense of why some people are transgender. And as long as don't result in prejudiced opinion I don't mind them. However, it is also important to be open to what science has to say about it :)
All the best for you.
Have a great week ahead!
