>>10, you can always ask those questions, but it's not certain that the OP can even answer them. And often that's not the point.

Let's talk about sexual orientation: unless you're bisexual, you will be attracted to either men or women, and your life will be shaped by these preferences. But can you explain them why you prefer one gender over the other by something that happened in your life, did you simply develop like that?

For many of such preferences, we are just born with them, and can't really explain them. The best we can do is to identify what works for us and and have the type of life that suits us the best, without always knowing why things are the way they are.
