I said I dont believe its genetic. I believe in my case it has something to do how the hormones in the fetus interacted with the developping brain.
whichever the cause of your homosexuality is, I can't see where the problem stands.
When I had my late coming out, my first thought was "what if I'm not gay? What if I'm following something that is not my nature?".
I remember a few friends saying that I should have tried to date girls and find out. I couldn't even consider to date a girl as an experiment to understand my sexuality. Answers came with time. Or maybe I have given myself answers that no one else could.
There is nothing wrong or right in this life. There is just your life, that's all. If you want to live it, do it in your own way and how it makes you feel good and how it is good for yourself. No one is born as a mistake.
You want to try to change your sexual orientation? try it. Keep in mind that trying to suffocate something that is part of you is not a recipe for happiness.
But don't enforce your choices because others are dissatisfied with you, or because they call you names. If someone is not respecting you, you should rather take distances from them because they are being abusive and they can become a threat to you.
It takes courage to follow your way of life.
