Everyone has everyone's feelings. Everyone's body secretes different hormones. We don't know what other people's inner thoughts are, their past and their growing background, so we can't judge others.

Maybe a girl, who experienced the horror of men in her childhood, won't have a good feeling for men, and then she will turn this good feeling to women. This is a very normal phenomenon. It is also the normal development of human psychology. People usually find a reliable support for their emotions. But this support is not necessarily a man. As long as you trust someone, you can rely on someone in your heart.
Now in many countries. Same-sex attraction has become legal, and they can get a legal marriage certificate like the opposite sex, which is protected by law, although we have not fully accepted it. It may be related to our traditional historical thinking, but I believe that one day, we will accept the beauty of this other emotion.
