Homosexuality is genetic in the sense that it is caused by epigenetics. Quote from Wikipedia.
“Epigenetics…is the study, in the field of genetics, of cellular and physiological phenotypic trait variations that are caused by external or environmental factors that switch genes on and off and affect how cells read genes instead of being caused by changes in the DNA sequence.”
However, homosexuality is not genetic in the sense that homosexuals are born with the “gay” gene.
One of the factors that can change genes is the power of the mind.
The mind can change genes. I know that sounds crazy at first, but here’s my source. It’s from Scientific American.
I’ll lay out my own theory on how straight people become homosexuals.
Have you ever wondered why straight people are sort of “attracted” to the same sex? Let me explain.
I’m straight, however, when I see a billboard promoting men’s perfume with a male model. I see that guy as an attractive man.
Women’s sexuality is quite different than a man’s. Have you ever wondered why women like to comment on other women’s beauty like when they’re watching a show or something. Men are averse to that sort of thing, men don’t comment on other men’s handsomeness.
For someone to self-identify as a homosexual. I think there are stages.
Firstly, straight people are already “attracted” to the same sex as I said before.
In the second stage, people sort of want to figure out their sexuality. They see people from their own sex. They try to make them look attractive to them. This is the stage where the mind kicks in and changes the person’s genes. Whether it be epigenetical changes or normal gene changes. (I lean that it’s just epigenetical changes though.)
In the third stage, this is where straight people find it easier and easier to be attracted to the same sex. My theory is that homosexuality is like drugs, the first time is hard. The second time is easier, the third even easier, and so on.
Well, you could ask, shouldn’t gays be bisexuals instead? Well, stats show that bisexual people are less open to admit their bisexuality than homosexuals.
I also think the percentage of homosexuals in Non-Western countries is lower than Western countries.
There is actually a “Gay Agenda” going on before all the bluster of gay pride we see today.
Homosexuality is normalized in Western countries, so that is why I think there is less homosexuals percentage wise in Non-Western nations.
This could also explain why there seems to be less homosexuals historically.

And here’s a good resource in defence of traditional marriage. Note that I don’t agree with everything in there. Especially his exegesis. https://youtu.be/iNBwDxCQwGk
Update: I found this article on the “fluidity” of female sexuality. http://www.patheos.com/blogs/theologyintheraw/2016/03/sexual-fluidity-understanding-womens-love-and-desire/
