This is quite a common "issue" among us survivors. And a difficult one to figure out, too, because of all the conflicting beliefs in society about the nature of homosexuality - where does it come from?
Everyone is uniquely different, and only you can determine for yourself what the truth is.
The best advice that I've been given about this is to not judge myself over it. Me, personally, the path I took was to choose to accept my sexual attractions, and to accept myself regardless. Because when I'm tidally locked between judgment and guilt, there is no room for me to grow and learn.
Here I am 20 years after accepting my sexuality and attractions, and dealing with my CSA, and now I'm wondering what my native sexuality is. I do so without judgment. I don't know if I'm gay or bi (could I be straight?). I just don't know. But I believe that with patience and kindness and non judgment, my true native sexuality will emerge all on its own.
But I have to accept the feelings and attractions and thoughts without judgment. That's part of the healing process.
I realize this can be very very difficult for someone who is Christian, and many Christians believe homosexuality is morally wrong. I won't debate religious beliefs. I will say, however, that I grew up a fundamentalist christian (southern baptist) and fought judgment and guilt. What a miserable way to live.
I decided that homosexuality was natural (it occurs in most mammalian species), and I accepted the expression of homosexuality in me as well. Made for a better daily experience in my life.
I hope you find peace of mind.
