i am openly gay 
Did you feel like your parents or early childhood had any effect on you being gay?
no not at all, i actually didn't really realize until i was 16 but denied it
Do you think that it is natural? Some scientists think that it is. 
i do it's common in animals so i know it was bound to happen with humans
That would make sense because there's a lot of evidence that shows it based on genetic and environmental factors  
yeah I totally believe it's genetic. I heard of a study that after a third pregnancy a woman's offspring have a higher chance of being gay
Well they don't know that for sure. It's really a complex interplay between genetics, hormones and environmental factors. 
i also heard about the twin study too
What was that? Twin studies are really helpful at determining the importance of environmental and genetic influences.
