Barbarian cites evidence:
Most data shows no direct genetic component to homosexuality, but there is considerable evidence for it being the result of hormonal imbalances during gestation. Certainly almost all homosexuals report knowing that they were so, from an early age. We still don't know for sure, but I think when the evidence is all sorted, we'll find prenatal conditions are very important.

I never saw how God would want His people to turn their back on truth. I know a lot of people think faith should be immune to reality, but in my mind, faith is completely in tune with the truth.
How odd...
As you see, right around puberty, where you'd expect it to be, if it was determined very early. I suppose that one of the problems of anecdotal information is that every now and then someone like you, (by chance, I'm sure) gets a completely skewed sample.
