Are we born with it? Is it somehow in our genes? Does it have anything to do with hormones? Are there any external factors that can affect it?

There is no good evidence for environment / upbringing having any impact on sexual orientation
They just released a study showing there is no single “gay gene”. They point to a few different genes which may be involved. I think nature and environment are at a fine balance on this one.
Nobody knows 100% for sure yet. There’s some evidence that genes are a factor, as well as environment/upbringing, but nothing conclusive. For example, identical twins raised in the same household can have different sexual orientations.
Environment might have a say in how one expresses sexuality but it has nothing to do with their actual sexuality. A lot of people have some memory of their sexual preference being established very early in life, despite being too young to understand or even feel sexual attraction. I grew up in an environment where being gay was not an option, so even though I clearly wasn’t straight it took me until I was 16 to even realize it. My first crush ever was for a guy friend of mine a whole 8 years earlier and yet I never thought about it until my late teens.
We don’t know exactly, but it’s primarily prenatal hormones. Pretty much every marker we have for that, along with random gender linked stuff show a difference in straight/bi/gay individuals. There’s a genetic component, at least for men. But it’s not a simple inheritance case like or bloodtypes. A gay man identical twin is twice as likely to be gay that a fraternal twin (50 vs 25%).
So just like how we know nothing about the formation of the universe, how exactly life on earth began really, what quarks are made up of, and whats really inside the Kravby Patty we have no real clue
